Zarrus was left on the doorstop of a blacksmith when he was young, when the corrupted dragon attacked Emeraldinia. He was trained in the art of being a blacksmith, and excelled at being innovative with his craft. He fashioned a furnace onto his backpack at the age of 10, mastered his craft at the age of 16, and he wandered around the world at the age of 20, where he met Cybern and Hekama. He offers his services as the Dragonfire Guild's heavy hitter and tanker. After learning of his Emeraldine roots, he learned about the ancient art of Emerald Power and vowed to bring his civilization back.
Zarrus wanders around the Overworld when he's pulled into the heat of battle with several Vortech minions. The rest unravels from there. (Main article: The Musings of a Wandering Blacksmith)
