Ilyria's right hand... man.
Eruk is a halfling rogue. He’s quite skilled at sneaking in and out of places undetected. His speed is high and he moves quickly in and out of people’s striking range to make his own attacks.
the party knows nothing of Eruk’s past
Eruk has been seen only once. He was by Ilyria’s side during the fighting in the Mt. Satendama mine and aided in her fight against Belevar Croogy. He then left with her to search the tomb of Fruian Dragonsbane. One could assume he was in Ilyria’s carriage when it crashed.
