Wraiths could be characterized as a loose taxon of species native to Nosgoth's Spectral Realm (excluding Archons, the Elder God, Sluagh, specters and tentacles). Some could manifest in the Material Realm, and all were distinguished by their blue blood. Both Malek and Raziel, in their latter incarnations, were described as wraiths. They, alongside other creatures referred to as wraiths, appeared in Blood Omen: Legacy of Kain, Legacy of Kain: Soul Reaver, Soul Reaver 2 and Legacy of Kain: Defiance.
