I am ally to Chardock (zone outside Chardock B) and wanted to see con for these guys. With agro from other mobs in zone the con was threatening. The con with no agro is indifferently. So just FYI
There is a group of four of these in a room past the castle entrance. They con indifferent but will assist. Not sure yet, but it appears all of the floating wanderers in this area spawn from this room.
