An article was posted on the Lodestone today about the upcoming instanced dungeons (or raids). These will be released in patch 1.18 and there is one intended for players around rank 30 and one intended for players around rank 50. The low rank dungeon, The Thousand Maws of Toto-Rak is the 30 dungeon and is located near Silent Arbor, while the 50 dungeon is located near Camp Dragonhead and is named The Dzemael Darkhold. The full details are below.

The Thousand Maws of Toto-Rak

Named for the thousand-mawed beast of Padjali legend—and in turn lending its dreaded moniker to a bygone warden of exceptional infamy—the endless cells of this notorious dungeon once held such heinous criminals as poachers and arsonists. Deemed barbaric and unworthy of Gridanians, Toto-Rak was abandoned and sealed three decades ago, its labyrinthine network of tunnels and shafts now given over to feral beasts.

The Dzemael Darkhold

Formerly an expansive system of natural caverns, the Darkhold was established when Count Dzemael of Ishgard recognized its potential as a subterranean fortress in the war against dragonkind. Work has since been ongoing to prime its vaulted chambers and rocky passageways for military purposes. Recently, however, word has arrived by way of leaked intel that troops of foreign origin have seized occupation of the Darkhold for an as-yet unknown end.
