A heavy diving helmet in a style common in Orkron. Through the small porthole, one can only see the unbearable and endless expanse of darkness.

Hands

A compass in the form of a wristwatch. The magnetic needle has been removed and can no longer point in any direction.

Body

A heavy diving suit crafted from scrap iron, airtight and impenetrable. Even its wearer often jests that it resembles more of a deep-sea coffin.
