Ruloi cave system

The Ruloi cave system, Ruloi Caves, or Ruloi Caverns, was the most extensive series of caves known on the planet Echelon. Thousands of miles long, the caverns were so massive that they stretched from the Calvo Peninsula on the Mainland to the continent of Zatal.

After the caves were discovered to connect the two lands in the early 19th century LA, travelers could make a dangerous pilgrimage to the tabaxi homeland called the Journey of Weeks.
