This is the main location of Baltimore's Nightmare quest. You can enter it by completing steps in Baltimore's directions. Master Baltimore kept his secrets, when he was alive. Before Thorak killed him, he wrote a letter, in game, notes.
- Thorak, if you're reading these words, it means you were finally my undoing. But know this, you son of a bitch...etc.
After looting this item, you will fight or leave.
