|A key to the front door of the lighthouse. (Horror from the Deep)|
The Lighthouse key is an item used in Horror from the Deep. It is given to the player by Gunnjorn, who is inside the Barbarian Outpost agility arena, after starting the quest and is used to unlock the door to the lighthouse north of the Barbarian Outpost. If and when you lose it, it can be re-obtained from Gunnjorn; however, you do not need to use the key to unlock the lighthouse after you have already unlocked the door once. This key cannot be attached onto the steel key ring.
