Set (Original Timeline)

Set was the egyptian god of evil, war and destruction. He is often represented having a jackal face. After Lara took the amulet off the coffin that he was imprisoned in, he and his power was awakened leaving it up to Lara to stop Set since she was the one that had the amulet that could keep him imprisoned forever but she had a time limit. She must imprison him before the solar eclipse or the whole world would have been doomed and everything would be destroyed.

Trivia

 * In the Prima guide for Tomb Raider IV, Set is mistakenly called Horus in the final level. Many guides make this mistake.
