The Silurians, also known as Earth Reptiles, Eocenes, Homo reptilia and Psionosauropodomorpha, were a species of Earth reptile. Technologically advanced, they lived alongside their aquatic cousins, the Sea Devils. Unlike other species, Silurians showed an important intraspecific variation (vast differentiation between breeds), such as the number of eyes, the formation of their pupils or the colour of their skin.
The Silurians were an extremely varied species, with different subspecies and appearances; there were at least ten or eleven Silurian variations. Whilst many of them appeared similar, there were subtle differences which were attributed to caste. There were also clans or families with differentiated physical characteristics, some suited for environments of extreme cold or high plateaus. In general, they were humanoid reptilians with scaly crests on their head.
One group of Silurians was found at Wenley Moor; these had long fingers and three webbed toes on each foot, and their mouths were small and sucker-like. The most noticeable feature of these Silurians were their three eyes. Their main eyes were bright yellow with cat-like pupils, while their third eye was red and high on the forehead, surrounded by a fluted bone structure. They also had rectangular external ears. They were active creatures who spoke quickly in deep voices.
Another group was found at Sea Base 4. They looked similar to those of Wenley Moor, but had stockier builds, brown skin, suckers on the tips of their fingers, smaller mouths, ornate, curving spikes around their heads and the third eye on top. The third eye would glow along with their speech, but was not used in attack. They were also slower and spoke in a higher-pitched voice.
A third tribe, found in Wales, was radically different in appearance. They had only two eyes, more human faces, no external ears, five digits on each hand and crests on their heads and down their neck. They had long tongues which they could flick to inject a venom, which was mutagenic to humans. They moved and spoke much like humans.
There were also the distantly related Sea Devils. They were genetically divergent enough to create problems for the offspring of matings with Silurians. Offspring suffered from biological problems including sterility and a shorter lifespan, due to cellular degeneration.
Some Silurians become darker green when blushing.
In at least one alternate reality, there was a human-Silurian hybrid. This demonstrated that mating between the two was possible.
Silurians were cold blooded and could only survive at warmer temperatures. They were sluggish and slow when cold.
Silurians had a hunter’s anatomy, with powerful muscles and hollow bones. Though they were taller than humans, they were also lighter and faster. Silurians were incapable of crying. The typical lifespan of a Silurian was 200 to 250 years, though some lived up to 300 years.
Silurians had an organ analogous to the human pituitary gland.
Most Silurians possessed a third eye on the forehead. The three eyes provided them with a triple-faceted form of vision. The top eye saw in infrared.
The third eye also allowed them to use a variety of telepathic powers. The Silurians used their third eyes to communicate with other Silurians in a process known as “linking”. The third eye would glow along with their emotions, becoming brighter when they were angry. They could sense the presence of other Silurians, even at great distances. Silurians could control the minds of other creatures. They could hypnotise and coerce humans through a link to a primal part of a subject’s mind, though stronger wills could resist this control.
The third eye was capable of harming organic beings, killing them or leaving them unconscious. Alternatively, they could revive a human that they had rendered unconscious with the third eye. Energies emanating from it allowed them to burn through walls and create tunnels.
The Silurians also employed their third eye in less destructive tasks, such as activating their technology, opening passageways or creating forcefields to trap prisoners.
Not all Silurians had these third eyes; a tribe found in Wales did not.
The Silurians were generally a peaceful race. Their highest laws forbade outright warfare except for defence. There was also great importance placed on the species’ pure eugenics, which was believed to be their most important principle and most sacrosanct belief. Breeding between a Silurian and a Sea Devil was considered a crime punishable by death. The eggs of such a union were usually crushed and the parents executed.
The Silurians were generally led by a Triad, three Silurians who ruled jointly. These Silurians came from different backgrounds and controlled different professions, such as the military and the scientists. Silurians were also split into different tribes. The majority of Silurian warriors appeared to be female, just as the females were the more aggressive in some species of lower reptile.
Silurians communicated by telepathically linking through their third eyes, as well as by body language. Though they could use words, they generally only used speech for effect, when talking to children or to species without telepathic linking abilities. Silurians had little in the way of literature, since their mind linking abilities were a more effective method of transferring ideas.
A Silurian of advanced age would festoon the third eye with pearls as a form of decoration. Some Silurians kept early hominids as pets. Whilst in the future, some used the term Earth Reptiles, others called themselves Silurians, insisting those that accepted the name of Earth Reptiles were pathetic assimilationists.
They worshipped a Lizard God. Their myths included Urmungstandra, a devil god and the Great Old Ones, including in their ranks Azathoth, a deity revered by the Silurians long before the rise of humanity. They wrote the Necronomicon. Madame Vastra once swore by a Goddess.
The Silurians made many advancements unknown to the humans.
The Silurians had advanced genetic capabilities. They brought species back from extinction, including many dinosaurs. They could modify species, as they did with the Myrka. They created a genetically engineered plague, which they once used against early humans who invaded their crop settlements. This disease was highly virulent and was used as a form of “pest control”. Despite this, they had problems with Silurian/Sea Devil hybrids’ deficiencies. They also altered primitive apes to make them breed more often and to improve their flavour when eaten; using these techniques, they ultimately ended up creating the ancestors of humanity.
The Silurians processed their own food and didn’t rely on harvesting animals or plants except in times of famine. The Silurians could bio-program soil, causing it to react to certain events and respond, generally by dragging people underground. They were capable of advanced decontamination, removing diseases and poisons from the body.
Silurians generally relied on their third eye for defensive purposes, using technology to enhance their power. (PROSE: Blood Heat) They used a Battlecruiser for transportation and offensive purposes.
The Silurians found in Wales used guns reminiscent of Sea Devil guns which could fire fatal energy beams. They also wore armour and used special masks that covered their faces and allowed them to scan objects.
- They had cryogenic technology which they used to preserve their civilisation when they believed the Earth was in danger. These had alarms for when the colony was threatened, (TV: The Hungry Earth/Cold Blood) though many were faulty and relied on nearby energy sources such as a nuclear reactor.
- They could use gravity bubbles to travel to and from the surface. They also had mechanical airships, which Bernice used and found to be of high quality.
- They had some holographic technology.
- They could modify the atmosphere, increasing the temperature in certain areas.
- They had the ability to disperse the Van Allen belt, which would have left Earth defenceless against cosmic radiation in an atempt to exterminate humanity, and unknowingly, almost every species of warm blooded creature.
- They could create force fields to trap an entire village, controlling the amount of light that got in (effectively making it night).
- They also had wrist devices.
- They had sophisticated spaceships.
- They invented candles which could enduce lucid dreams, allowing people to communicate across time and space.
The Silurians were the original masters of Earth. They were led by the Triad and used the The Sea Devils as soldiers. In the early era of their rule, there were many stories of the rise of their civilisation. One noted legendary warrior chieftain was Masz K’ll of the Third Dynasty, who fought against his evil alter-ego, the legendary Two-Faced Lizard. Another figure was Panun E’Ni, who was the leader of the Southern Clan and conquered much of the world, which he ruled cruelly for a brief period until his defeat at the hands of Tun W’lzz. Following that event, the previously imprisoned and cast out tribes came together in a new, more unified civilisation that ate their foes. Whether these were folk stories or historical facts was of no importance to them, as they inspired the Earth Reptiles for a millennium, with many of these writings left within their Hall of Heroes.
In this era, the Silurians co-existed in groups of clans that lived alongside the original ape primitives that were developing on their planet. As a lesser species, these hominids became the primary livestock of the Silurians. In order to improve their flavour, a Silurian scientist by the name of Tulok began to genetically engineer the apes. This led to a faster breeding cycle as well as intelligence, creating early Homo sapiens. For his genetic crimes, the Silurians banished Tulok and his creations to die in the coming cataclysm. These primitive, ape-like men began to hunt in packs and attacked the Silurians. They also began to prey on the crops of the Silurians, leading the Earth Reptiles to use plagues to exterminate them. The Silurians were also afflicted by the plagues of the red leech.
At the height of their civilisation, the Silurians lived in cities of metal millions of years old, and had uncontested dominion over the planet. However, this era was cut short. Some of their scientists, such as Doctor Wolik, believed that a small planetoid was destined to crash into their world. Some Silurians doubted this coming disaster; a few believed it to be a simple scare story. Eventually, the Silurians panicked. They entered hibernation chambers so their civilisation could survive the coming disaster and reclaim their world once the danger had passed.
One group of Silurians decided to leave Earth in order to escape the disaster. Boarding the Silurian Ark, a spaceship carrying Silurians and several species of dinosaur, they placed themselves in suspended animation, with the ship programmed to bring them back to Earth long after the effects of the upcoming disaster had dissipated.
Twelve years before the large planet came dangerously close to Earth, the Silurians were divided on the matter of a mating between the land castes and aquatic castes. Normally, such matings were forbidden, and any offspring were killed along with their parents. However, facing the threat of a global cataclysm, they allowed a colony of such hybrids to remain in their Shelter near Smallmarshes. With the rest of the Silurian race, they took part in the Great Hibernation. The panicked Silurians sealed themselves in their underground hibernation chambers, but the technology was faulty, and never woke them. They were unaware the dangerous planetoid that they believed would devastate their world was instead captured by the planet and became the Moon. Despite their intentions to punish Tulok, the renegade Silurian scientist instead sabotaged a number of the hibernation chambers and destroyed them.
The Arkive tried to attract the Silurians to Saturn in order to repair itself. Though the Silurians noticed one of Saturn’s moons being destroyed, they were too busy preparing for the disaster to investigate.
Over the millions of years since their rule, many of the Silurians’ prominent structures such as the Hall of Heroes were lost to erosion and plate movement which erased any traces of their ancient civilisation. After millions of years, some of the Silurian Hibernation units were activated and opened.
In 102, a number of Silurians were part of the Alliance of the Doctor’s worst enemies that imprisoned the Eleventh Doctor in the Pandorica.
Charles Darwin and the HMS Beagle expedition, along with the Sixth Doctor and Evelyn Smythe, encountered a rogue Silurian group in the Galápagos Islands. The leader of this group had been responsible for creating humanity’s prehistoric ancestors via a forbidden breeding program.
Prior to 1888, a group of Silurians was awoken by the digging of the London Underground. This led to the death of several navvies. Vastra, a skilled Silurian warrior who had been awoken by their digging, wanted revenge. The Eleventh Doctor convinced her to live peacefully in London. In 1888 she resided with her human partner Jenny, although she fed on human criminals. Then, she and several of her soldiers were called up by the the Doctor to fight at the Battle of Demon’s Run.
In 1892, the Silurians led by their leader Vekkis found a piece of the Eternity Clock to reclaim Earth. They planned to use the power of the Clock to pump toxin to wipe out the human race. The Eleventh Doctor and River Song destroyed the toxin and took the Eternity Clock.
Jules Verne and the Doctor once encountered Silurians and a giant squid. This incident was worked into 20,000 Leagues Under the Sea, though the Doctor had some difficulties convincing Jules to remove the parts with the Silurians.
In 1903, after receiving a wealth of information from the future, Grigori Rasputin saw beings which lived beneath the surface of the Earth.
In the late 20th century a group of Silurians were awakened from hibernation by the energy from the nearby nuclear power research centre at Wenley Moor. After disagreement between Okdel and Morka over a course of action, Morka won out and the Silurians tried to reclaim the planet from humanity by releasing a deadly virus. This plan was prevented by Brigadier Lethbridge-Stewart of UNIT and the Third Doctor. Despite the Doctor’s best efforts to broker a peaceful solution, the Silurian base was bombed by UNIT by order of the Brigaider. Shortly afterwards, a second base was awoken in Oregon, and was likewise dealt with by UNIT. A different base of Silurians was found in the Smallmarshes. This group consisting of hybrids born of unions between Silurians and Sea Devils. They too wanted to take back the Earth. There was a power struggle until The Third Doctor managed to ensure that this shelter was left in peace and there was an end to the fighting.
In 1983, Sarah Jane Smith and K9, while visiting Warren Martyn’s archaeological expedition in Egypt, discovered an underground city of Silurians and Sea Devils. Sarah Jane opened diplomatic relations with them. On her return to England, she contacted the Brigadier, who wished to make amends for his earlier mistakes.
By 2003 there were Silurians serving as part of UNIT, in particular Imorkal, who worked with Liz Shaw at Tranquillity Moonbase located on Earth’s Moon. Some decades later, Sir Alistair helped the Silurians try to finally make peace with the humans, though the general public believed it to be a stunt involving men in rubber suits. Later, the Silurians aided UNIT in finding a cure for a plague.
In late 2010, a fossilised Silurian egg was discovered by the Pharos institute. Sarah Jane went to the institute to take a look at it.
In 2020, a Silurian city in Wales was awoken by a mining trial led by Nasreen Chaudhry and Tony Mack. The Silurians took corpses from a graveyard for study, as well as Mo Northover and later Amy Pond as living subjects. Eventually they contained the village in a force field and captured Elliot Northover. Alaya came to the surface and was captured. While the Eleventh Doctor and Nasreen travelled to the Silurian city to negotiate her return for Mo, Elliot and Amy, Alaya was guarded by Tony, Rory Williams and Ambrose Northover. The Eleventh Doctor and Nasreen were captured, while Amy and Mo escaped. After an abortive rescue attempt, the Doctor was able to convince the Silurian leader, Eldane, to negotiate with Amy and Nasreen for the future of both their races. Back on the surface, Ambrose tried to help her family and threatened Alaya, accidentally killing her just as the group were summoned to the city. Alaya’s death was received badly, especially by her sister, Restac, who tried to kill all the humans in retribution. Eldane managed to lead the Doctor and his friends to a laboratory. He released a deadly gas into the city, forcing Restac’s troops to return to their hibernation. The timer was set for a thousand years, to permit a second chance at negotiation.
Circa 2084, a group of Silurians allied themselves with the Sea Devils to invade Sea Base 4. They attempted to launch nuclear weapons to provoke a war between the two major power blocs. They were killed when the Fifth Doctor, perceiving no more peaceful option, flooded hexachromite gas in order to kill them.
At some point after the 2084 incident, a human colony faced a devastating war against the Earth Reptiles. Humans developed a doomsday device which they placed in a base around the moon colony, designed to scour the surface of the satellite. To combat this, the Earth Reptiles dispatched Quarra to infiltrate the base and take it over. However, she was unaware of an entertainer called Jen Yates who was not on the crew count, and this last survivor managed to activate the weapon, killing everyone in the colony. Though Quarra killed Jen, the shock of the event led to Quarra taking on the entertainer’s personality to shield her from the truth. She believed that she was now human and that she was guarding the weapon alone in case the Earth Reptiles won the war. After a visit by the Seventh Doctor, Quarra remembered the past and killed herself by walking onto the surface of the moon without a spacesuit.
Around the 24th century, Solomon sent a distress signal to the Silurian Ark. Realising that there were valuable dinosaurs on board, he and his robots killed the Silurians on board. Unable to pilot the ship to his destination, the ark headed back to Earth.
By the 26th century, the inter-species conflicts appeared to have come to an end. Silurians and Sea Devils were accepted into Earth society, and the term “Earth Reptile” was apparently popularised among humans.
During the 29th century, when solar flares were threatening to engulf the Earth, the Silurians built a spacecraft, surreptitiously attaching it to the bottom of the humans’ own. After takeoff, a Dalek attack caused the Silurian ship to break away from the humans.
In the 30th century, the Earth Reptiles were part of the Earth Empire, considered full members of the government as an Earthborn species.
In the year 3020, one thousand years after the encounter at Cwmtaff, Eldane’s clan were scheduled to reawaken and unite with humanity and their Earth Reptile cousins.
In the 32nd century, it became illegal to trade in Earth Reptile pituitary analogue extract on the planet Dramos.
In 3110, a Silurian was running the Musée d’Orsay when the Eleventh Doctor visited it.
Around the 52nd century, a group of armed Silurian warriors resembling those from Wales were called upon by the Eleventh Doctor to help him in the Battle of Demon’s Run to rescue Amy Pond. Many of these Silurians were killed by the Headless Monks.
In the 101st century, the Earth Reptiles were part of the Union.
