Mithrillian Mines--

Mithrillian is an extremely precious and valuable metal mined here. More compact than mithril and highly explosive, mithrillian can be used in many ways. However, Osirus long since took over the Mithrillian Mine and now forces thousands of people to work here in the poisonous caves. Food, water, light and air are scarce and escape is rare. Thos who survive the Blood Chamber and jail are often sent here. But in order to promote faster shipping, Osirus has placed thousands of women and children in here as well.
