Dang.. beat me to it.. lol. Wont even post a screenie, cuz we got like the exact same pic too. Was curious about any drops.. I didnt see anything on corpses, and the Shadowlords just gave the usual cloaks.
I did happen to come upon "The Prisoners Journal" (blessed purple book) which was lying among the other books in Luna. Browsing the book, it looks like something to do with those NPCs that live in Moonglow..
Was this from a prior event and just disgarded by someone? Or somthing that just *appeared* from the Luna invasion?
