You are a servant of the Divine One. You are the scourge of necromancers and sorcerers alike. Your purpose in life is to fight all that is evil using any means possible. During an intense battle with one of the great necromancers, however, a demon drags you into its universe where you are soul-forged with a Death-knight.

You are cursed and destined to spend the rest of eternity bonded to this creature of evil... Unless you embark on a great adventure to uncover the secrets of riftrunning, an ancient art that allowed the indigenous population to travel between universes.
