Dunbarrow Cove (Location)

Overview
Dunbarrow Cove is a cave located behind and under Castle Anvil (as pictured). The first section of the cove is called "Smuggler's Cave" and contains some crates, barrels and chests. The lower passage leads to Dunbarrow Cove itself, while the upper passage * leads to a secret section of Castle Anvil and ends up in the Umbranox private bedchambers.

* Can only be opened with the "Smuggler's Key" which is found in the chest at the foot of the bed inside the Captain's Quarters after having been upgraded.

The Cove
Dunbarrow Cove houses the infamous Black Flag and becomes a "house" of the player once it has been cleared of Red Sabre Skeletons (see Dunbarrow Cove (quest)). It can then be upgraded with NPC's and a proper Captain's Quarters by talking to Dahlia Rackham at the Sea Tub Clarabella.
