Jahakinir the Shadow-Wizard, a lich of terrible power, created the first four shadesteel golems on the plane of Mabar, the Endless Night, and offered them to his vampiric apprentice, Osilvune. He then sent his apprentice forth to raise a kingdom on Eberron. Osilvune became ruler of her own demesne, but her ambition brought her too many enemies. One day, she simply vanished from the face and depths of the world. Her servants claim that she hid her wealth in secret subterranean vaults guarded by Jahakinir’s shadesteel golems, but these sepulchers have never been found. Whether the lich created other shadesteel golems and whether the secrets of their construction have been passed on remain mysteries as well.
