I have a PC with the Exposed to Awfulness trait but a quest tied to it really doesn't fit so I am looking to make an encounter more tied to his backstory.
Basically this PC is the forsaken child of the early game villain in Rise of the Runelords.
This villain met their final end in the Darklands and were buried along with a small clan of duergar under tons of stone and irradiate crystals via an Earthquake spell.
Needless to say their spirit was forsaken by their deity and risen from the dead as a powerful godless undead seeking their child to murder them thinking this might end their horrible existence and return to Mother's Grace.
Anybody got any monster suggestions?
