Dark lord of power and malice
Karevos Malevolence was once a simple mage, born in a time since forgotten. Said to contain a cruel heart, Malevolence practiced dark magicks, and soon became a powerful lich. Conquering homeland after homeland, he was a dark and powerful being, slaying mortals, monsters, and gods alike. His power grew steadily, and he soon attained what amounts to evil godhood in his domain. His evil influence slowly spread to other worlds and dimensions, corrupting those of weak will, and inflicting death and chaos everywhere he could. Nigh-invincible, he eventually came to conflict with Thrane Morgan, a god of good and light from a minor plane. As Malevolence crushed Morgan’s forces, Thrane employed a desperate and devastating tactic; he sacrificed his own godhood to tie Malevolence to a phylactery, the Grobani Crystal. While this did not defeat Malevolence in its own right, it did bar the being from taking most actions without the aid of mortals willing to sacrifice life-force, limb, and will to the now-tainted object. Morgan gave the last of his power to his most faithful servant, Gorion Watts, and charged him with the important task of being keeper of the Grobani Crystal, and thus, Malevolence’s jailer.
