Yeah, a chest appears in the sidepath immediately to the west when you enter greenwood. Don't remember what it was though, probably a potion of some kind. Maybe the back demon door close to the boast podium opens when the statue points at the guild? Maybe should check that out...
Its a pericing agumentation, and it will also point to bowerstone, and when it points there the tavern celler doors will open, and that demon door was apparently to lead to the northern wastes here the dragons were supposed to be but they forgot to take it out before the game was finished.
And lo ye must learn of the great war that raged fo a couple of posts and brought the citadel momentaraly to its knees Lookie!
I tend to appear briefly and disappear very quickly after that, try not to let it bother you.
