The Chosen One's Assistant

Never meet your heroes. Outcast by every guild, starving, and left beaten and shamed in an alley, he was beyond desperate when the timeliest opportunity presented itself: The Greatest Hero of Men was in need of an assistant. He was so eager to leave his old life behind, he didn't hesitate to accept the role of Tiberius, personal assistant to The Chosen One. The magically binding contract was signed, and the previous servant was out the door before the blood on the quill was dry.
Tiberius quickly learned he was responsible for all of the hero's needs from mundane to absurdly ridiculous, and the hero himself was the most ridiculous of all. Woefully inexperienced as a quester, thrown into the hero's world of danger and debauchery, he could never have guessed how harrowing and frustrating this new position would be. Then he learned the God of Pestilence was holding a well-justified, 100-year-old grudge.
Death, disease, and evil beyond any Tiberius could imagine awaited them on the path ahead, and The Chosen One had been called to stand against it. How could Tiberius hope to survive his first campaign with the gods' champion against Trion, God of Darkness?
