The strange Blackstone Island workshop is securely closed. The bizarre constructions within were the result of the previous inhabitants' nasty schemes. They are now unoccupied and abandoned. You may utilize them by using this key.

Access is therefore granted to the following things:

• Arterial Engine - The bony blades of this grotesque engine are driven by a pulsing heart. It beats in time with your own.
• Sign of Ruin - A symbol of the deep is carved into this small talisman. It's sure to draw the attention of those attuned to it.
