Holm is a "dungeon balancer" who is responsible for maintaining the ecological stability and monster refresh of classic dungeons visited by adventurers. His tasks include: providing pre-job training to goblins, touching up the paint of Mimics, mediating territorial disputes between the orc chiefs and beholders, and even secretly distributing "memory spring water" to dying elite adventurers to help them retreat. He wants to ensure that the dungeon is challenging and rewarding enough, but not so much that the adventurers are wiped out or the monsters are slaughtered, maintaining a dangerous "sustainable adventure."
