King Tyras is the overlord of West Ardougne and the brother of King Lathas. He has yet to be seen in the game but plays a part in the Plague City series. During the quests, he leaves his city and creates a camp south of the Isafdar forest called the Tyras Camp. In the quest Regicide, you must assassinate Tyras. His camp is populated by Tyras Guards. After you kill him, it is revealed that he is not evil.
