Lord Desmond

Real name Q'taar'ius we know him as Lord Desmond (deceased, kinda) was a prominent politician in Deastock and the original betrothed to Cecilia Loden. At least the physical body he is inhabiting was. He might also be the Lord of the Nine Hells, aka The Devil Lord. He is definitely not mortal, and is as old as time possibly. 
Lord Desmond had incorrectly told Count Loden that Greg had killed his daughter. In actuality, Lord Desmond had hired assassins to kill Cecilia in order to assert his control over the Porteau family since he was unable to marry her.
