Hellfire Rift

Hellfire Rift is an inhospitable plain of lava pools and rivers of molten rock which is located south of Hilt and empties into the Bay of Storms.

The ruins of Alabastia can be found some distance within the lava flows.

In Blade of the Avatar, Syenna mentions a legend that speaks of multiple passagess through the Hellfire Rift known as the Paths of the Dead. It is currently unknown if these actually exist.
