Nightmares of Nerath
Former Karkothi warrior, now undead Mummy.
Gerennus Failbhe (Wolf Slayer), was a Karkothi warrior who betrayed his own people to save the Harthyar Barbarians of Western Selduria.
The party encounter the mummified undead form of Gerennus when they come across a cursed finger (belonging to Gerennus) which results in nightly attacks from the former Karkothi.
Each time he is killed, he returns the following night, stronger than before.
The party have tracked down the location of his resting place, to a tomb 10 miles to the South East of Woldred’s Hold, in Ghostdrake terrority.
