Gutsco

Gutsco appears in the Subterranean Lake and has stolen one of the dwarves' Horns of Ice. After he is defeated once, he follows you as a shadow to the Dwarven Hollows until they approach both Horns, where he reveals himself and promptly steals both of them. You pursue Gutsco with encouragement from the dwarves, but Gutsco escapes. He runs to the Molten Cave, where he heads to obtain the power of the Fire Crystal now that he is protected from the cave's hostile magma thanks to the Horns of Ice. The Warriors of the Light find him at the crystal room in the depths of the cave, and fight him in his state of empowerment granted by the Fire Crystal where he takes the form of the Salamander. Despite becoming more powerful, he is defeated once again. Male. Evil. Demonic.
