Culling of Stratholme is empty, and npc's are probably (and surely) not sctripted or loot eligible. Actually a few arent in the database. So that needs attention, plus the gameobjects (gates and the bookshelves) arent clickable and thus progress thru the instance come to a hault.
Note on Violet Hold: End Boss Dragon drops T9 piece for Druids. NOT suppose to be there lol.
