Tulok
Tulok was one of the chief scientists of the Silurian race.
He was present on Earth when his people held dominance over the planet when Humankind were simple apes that became his race's primary livestock and food source. Tulok used genetic engineering to improve the creatures' flavour by increasing their breeding cycle and intelligence. This, in effect, resulted in the creation of modern Humans. However, in doing so, Tulok broke one of the highest tenets of his people, which was tampering with nature. As a result, he was brought before the Silurian Justice Chamber for genetic crimes. It was held that Tulok was to be exiled along with his creatures to die in the wilderness at the time when a planetoid was approaching Earth which would have left the surface uninhabited for a period of ten years.
Tulok managed to survive these conditions and wreak his revenge by sabotaging the hibernation chambers of his people, which destroyed all but a dozen or so. (BFA: Bloodtide)
