Raziel

The Soul Reaver is Kain's ancient blade that harbors the spirit of Raziel's soul. It is a flamberge-class sword with a broad, undulating serpentine blade. Raziel is a wraith that is now trapped in the Soul Reaver sword and is unable to leave it, however, his soul allows the weapon to have access to spectral related abilities that grant the owner of this sword the ability to see ghosts and visit the Spectral Realm.
