Resurrection Runorm
 

I have found this runorm come back alive again in verlon wasteland..but i dont get any quest related to him, the only choice is kill him..i feel it may have quest latter on, but i cant find it..is there any development or quest related for this after demonis?

I killed him too. Got some exp and gold and done. ^^ He was in the cave (spider cave) in Verlon Wasteland. I had to walk a bit into the cave, he has his own small spot there.
