Profile - Summoned demon

Centuries ago this demon waged war against humanity, eventually losing to demon hunters like Gertrude Rosenfeld. He fled to the demon realm, vowing to reclaim rightful control of the domain that was usurped from him.

Many years later, he finds himself summoned by a hapless man who wishes for power to take revenge against his foes. Seizing the opportunity, he provides his support while executing his agelong scheme to take back what was his.

This is part of the New Salem universe.
