Tulok was one of the chief scientists of the Silurian race. (AUDIO: Bloodtide)
He was alive on Earth when his people held dominance over the planet, when humankind were simple apes that were 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 resulted in the creation of modern humans. In doing so, Tulok committed one of the greatest crimes of his people, tampering with nature. He was brought before the Silurian Justice Chamber for genetic crimes. Tulok was exiled along with his creatures to die in the wilderness at the time when the Moon was approaching Earth, which would have left the surface uninhabited for a period of ten years.
Tulok survived this sentence and wreaked his revenge by sabotaging the hibernation chambers of his people, which destroyed all but a dozen or so of them. (AUDIO: Bloodtide)
