In Blood Omen, Bane was the Guardian of the Pillar of Nature, and he dressed in animal skins. His power was connected to all things natural - plants and creatures, and even the weather. He was able to "change the nature of life itself, animating plants and influencing animals, creating new and weird life forms for his own purposes".¹
Like his fellow Guardians, Bane had been afflicted with madness by Nupraptor's grief-fuelled attack. In his insanity, Bane used his magic to devastating effect. He allied with DeJoule and the Alchemist Anarcrothe, and created decidedly unnatural beings in the area around Dark Eden. Their combined sorcery spewed from the apex of Dark Eden's tower, and rained down onto the region.
Kain found Bane standing with the others in the tower. Anarcrothe summoned Malek and fled. Kain called upon Vorador, then he pursued Bane and DeJoule as they also tried to escape. He confronted them both outside.
The fight took place in the open air, in an area containing water and earth. Bane used the location to his advantage, stripping away pieces of the ground to reveal the water beneath. The process made it difficult for Kain to battle. He had to catch Bane to strike him, but he had to avoid the deadly water traps that the Druid was laying for him. When Kain killed Bane, he collected his broken Antler Headdress (damaged in the fight) to repair the Pillar of Nature.
