Troilus came from the town of Lydes. When The Breach opened up in the sky, he found the rifts it opened so interesting that he decided to study them. In his diary, he refered to the rifts as "the Menace", and called investigating them his "Great Mission". He took interest in the Rifts at the Pavilion. When he approached one of them, it was inactive. He assumed his studies of the rifts would allow him to close it. However, he failed and ultimately died at his camp near the rift.
