Johanhus Ulsbrecht is the leader of the Humans Against Monsters cult. He can be found inside the H.A.M. Dungeon in the southern room behind a desk. He plays a somewhat small role in the One Small Favour quest, and is a major character (players do not need to speak to him directly) in the Dorgeshuun quest series.
Johanhus remains the leader of the passive faction of H.A.M., only petitioning Duke Horacio of Lumbridge to turn against the Dorgeshuun but not taking any direct action for fear of punishment. He also seems less encouraged of the idea to wipe out all of the goblins.
His robes are dark red, rather than pink like the other H.A.M. members wear.
