Castrum Meridianum is a 8-party Dungeon Dungeon in Final Fantasy XIV: A Realm Reborn, and, along with The Praetorium and Cape Westwind, wraps up the main storyline of 2.0 and the Seventh Umbral Era.


Castrum Meridianum Baileys.

So begins the third phase of Operation Archon, which entails a frontal assault upon Castrum Meridianum, Gaius van Baelsar's seat of power. Forming the main thrust, the Immortal Flames will strike at the stronghold with all their strength, though this is but a feint. While the garrison's eyes are drawn outwards, you and your comrades must steal past its defenses and attempt to deactivate the magitek field which protects the Praetorium, the fortress within a fortress wherein the Ultima Weapon is believed to be housed.
