Glough's key is an item used during The Grand Tree. It opens a chest in Glough's home just south of the Grand Tree itself.
Players obtain this item by talking to Anita in the Tree Gnome Stronghold. Her home is in the north-west of the stronghold, just west of the swamp. The key has no use after the quest, but it can be re-obtained at May's Quest Caravan after putting 150 quest points into the Hub Track.
