The pit

Secreted away on tsunami island stands a great temple.  An ancient
man stands here for eternity.  He guards the way to The Pit, a great
tournament which holds warriors from across the realms.  The keeper
warned me of the great dangers which were held in The Pit.  His
words struck me deeply, and alas, I was too afraid to confront the
dangers of The Pit myself.  If you find this temple, I'm sure that
you can gain more information from the keeper.
