Mortwights are spirits of those who died extremely violent deaths. Their rage and anger towards their death causes them to awaken in the Shadowlands as Spectres, never existing as a ghost. Many Mortwights had dark natures to begin with, and some believe they were destined to be Spectres from the beginning.

The Orpheus: Orpheus Rulebook Bullet-pdf Bullet-nip introduces Frighteners, who resemble the majority of Mortwights at first glance that both kinds of Spectres have met violent ends. However, the Frighteners differ in actually having been humane when alive and driven into Spectredom by the horrific circumstances of their deaths.

They appear in both Wraith: The Oblivion and Orpheus.
