Sohr Khai is a dungeon in Final Fantasy XIV: Heavensward. It will be added in Patch 3.3.
Majestic and forgotten, its existence unrecorded in the annals of man, a palace rests atop the clouds in the farthest reaches of the Churning Mists. This skyborne splendor was once home to Ratatoskr, brood-sister to Hraesvelgr and Nidhogg, until the treachery of mortals ensured that its stones would never again ring under the she-wyrm's talons. The dragons named it "Sohr Khai," a grieving apology for their failure to avert her fate, and they watched with infinite sadness as Ratatoskr's empty roost was overrun by bird and beast.Duty Finder
