Cryx: Deneghra, The Soul Weaver

Deneghra, the Soul Weaver takes 
to the skies to terrorize her foes. Atop her nightmarish winged necromechanikal mount she blots out the sun, casting a long shadow over those destined to die by her command. She gathers the souls of those slain in her presence, twisting them to her malevolent will. Such is her mastery that she can send these tormented spirits to empower her machines or tear their essence apart to weave a torrent of withering magic.
