The Sunken Temple of Qarn is a dungeon in Final Fantasy XIV. This dungeon is accessed by starting the quest "Braving New Depths" in Vesper Bay at level 35. The dungeon complex is located directly east of Little Ala Mihgo in Southern Thanalan.
Under the unforgiving Thanalan sun lie the ruins of an ancient temple half-devoured by the shifting sands of a timeless desert. Though used by ancient Belah'dians as a place to worship the sun goddess, Azeyma, the massive underground structure appears to be far older than this Sixth Astral Era civilization. That, however, did not deter Belah'dian sultans from each adding their own chambers to the original construct in a bid to achieve immortality through creation. In the subsequent years since the fall of Belah'dia, many an adventurer has sought to explore the temple's mysteries and perhaps return with the reassure of a loser era... only to fall victim to one of the complex traps set to prevent that very thing from happening.
- —In-game description
Introduced with A Realm Reborn, this dungeon was among the few not originally part of the Main Scenario, serving as filler for mid-30s. However, in Patch 2.1 one of the Main Scenario quests for A Realm Awoken has players visiting this dungeon to recover a wardstone for Slafborn of Revenant's Toll.
