Treasury of Erebus

The Treasury of Erebus was a belief among the ancient Vulcan people that concerned the peak of Mount Seleya. Many of these early Vulcans believed that the peak of the mountain contained the lair of a terrible ice demon. (TOS novel: Vulcan's Soul Exodus)


 * Considering the origin of the Romulan people, its possible that this myth inspired the belief in the Halls of Erebus.
