The Fabled Cave (Japanese: おぼろの洞窟 Hazy Cave) is a location in the Hoenn region, found on a large island situated in the bay east of the Seaside Cycling Road on Route 110 (or southeast of Mauville City) in Pokémon Omega Ruby and Alpha Sapphire. It is only accessible by soaring on LatiosOR or LatiasAS and appears when the player has a level 100 Pokémon on their team.
In the back of the Fabled Cave floats a "mysterious ring". The player may interact with this ring to battle ReshiramOR or ZekromAS.
