For two centuries, Krag was a ghost in the Underdark’s arteries, a merchant of 'The Quiet Sleep'—a toxin so subtle it could erase a Drow House between heartbeats. He lived for the clink of platinum and the thrill of the unseen, a hollow man who viewed genocide as mere logistics. His conscience was a numb, calcified thing until he walked through the silence of a Svirfneblin mining colony he had inadvertently helped poison. There, amidst the unmoving dead, he found a rusted music box still playing a tinny, broken lullaby in the hands of a child. The music didn't just break the silence; it broke Krag.
He discarded his stealth for the thunderous clank of penance. Krag commissioned a suit of heavy plate, far heavier than necessary, and swore to wear it until his legs failed or his debt was paid. He hammered his finest blades into 'The Merciful Chisel,' a massive tool of protection, and took an oath of non-violence. He now wanders the lightless tunnels as a beacon of unwanted mercy, shielding those whom the world has deemed 'expendable'—goblins, kobolds, and even the very Drow who once employed him. He is a man terrified of his own shadow, praying that the killer he once was is truly buried beneath the steel.
