Going to fill out a bug report tonight when I have time but there is something seriously wrong with the whole area the quest is in. First off Aries soul never spawns but second there is major lag there and the game crashes if you go to far into the caves. Also when I asked around in zone chat I learned that people were actually getting stuck in the cave and couldn't leave or something, resulted in having ZOS support move their characters out.

So for now I abandoned the quest. Was this quest bugged before this first big patch? Im thinking it has to be with the way you get the quest. Usually there is one quest marker. Well with this quest in daggerfall Stormhaven there is at least three that I know of, two chests outside the cave and one from the soldier spirit in the cave. There whole area is just a mess. We are calling it the Bermuda Triangle.
