I ran across these in fw they were light blue to my 53 mage and there is a quest giver who also gave the quest to Evilinn near a tree in forkwatch named captain abigail
she asks for four ore that the hill giant invaders drop and rewarded Peyton with 800k for four plus some tunar.I was told for Evilinn to go to hazinak when I got there the only thing I found was a portal didnt see any giants at the time so I dont know.All in all easy quest with decent xp=D FYI The ones who cast are kinda mean the ones in fw were green to evilinn and still gave badi a bit of a fight so careful pulling more then one on a lower toon;)
