The Troubled Lands
Vysys Thrynn is a half-devil thief, an agent of the Thieves' Guild. He was dispatched by the Guild to oversee their investment into Captain Elbi's expedition to the fallen dwarven fortress of Anvilmount, and ensure its safe return. Most of the expedition was lost, but Vysys and his companions successfully breached the Vault of the Mountain King, recovered its treasures, and brought the Guild's investment home.
After meeting Caris, the inkshaper, he has been tattooed with the Mark of the Lodeseer, a magical tattoo that gives him power over metals. After losing an arm to the corrupting influence of the god Ruin, he uses this power to control a mithril gauntlet crafted by Silas in place of his missing hand.
