Fall and Rise of the Eternal Empire
One of the leaders of the Red Hand Horde
Koth found himself in his current position after his former boss lost the Stone Tooth to Gimor and his army of dwarves. As a result this hobgoblin is highly motivated to be victorious. He is known for being particularly cruel; he frequently orders the mutilation of captives in an attempt to intimidate his enemies.
He was defeated by the party at Vraath Keep and barely escaped with his life. His current whereabouts are unknown, although Sly did keep a scry focus from the combat.
