Treytrum joined a guild of assassins at a young age. He made tons of money off this career for years, and became a very experienced assassin. After a while, Treytrum would stay in the guild's headquarters than his actual house, because it was too much of a risk to be seen in public. One night the headquarters was tracked and found by authorities. He managed to escape through a trapdoor quick enough to not be seen. By the end of the night, he was the only assassin left of his guild.

After realizing the magnitude of his previous actions, he sailed off to a small town named Harton to start a new life. He took up a couriering job because he thought it'd be fitting of his skills.
