“Situated upon Vylbrand, Castrum Occidens is more akin to a research facility than a fortress. Even before its pillar was driven into the ground, Legatus Gaius van Baelsar had ordered his people to probe the fragment of Dalamud which fell at that precise location. The impact resulted in the creation of vast caverns pervaded by corrupted crystals. Though unknown dangers lie in wait within, you must brave them all if you are to learn the truth of the Calamity.

Enemies
Bosses
ADS
ADS, Allagan Defense System, is the mini-boss of Turn 1.
High Voltage : Inflict moderate damage to all players and apply 
Paralysis, which will periodically 
Stun the affected player and cannot be cleansed. Interrupt the cast at all cost. Blue Mages can learn this spell.- Repelling Cannon : A pointblank AoE from the boss
- Piercing Laser : A line AoE aimed on a random person
- Nodes : Adds will spawn on the entrance and will tether to the boss if they get too close causing the boss to regenerate some HP and gain increased damage done. Several variants may spawn though all of them will cast Repelling Cannon similar to ADS.
- Enrage : ADS will explode after 4 minutes(4 clicks), dealing massive damage
Caduceus
Mechanics
- Crystal Platform : The yellow crystal path that you've been walking on before will glow and apply a
Bleed to anyone standing on it when Caduceus is active. - Hood Swing : Non telegraphed cleave tankbuster with a large radius
- Whip Back : A telegraphed backward cleave used when a player is standing behind it.
- Regorge : Spit a
Poison puddle on a random player that deals damage over time. - Steel Scales : Caduceus will periodically gain a stack of Steel Scales, increasing physical damage dealt by around 50%. This buff does not expire on its own and will stack up to 8.
- Dark Matter Slime : Several of the platforms will begin to glow and when it finish, anyone standing on top of these platforms will spawn a Dark Matter Slime. These adds will fixate on the player spawning them and explode if the target is too far away, dealing massive AoE damage. If Caduceus comes in contact with these slimes, it will
Devour the slime and lose a stack of Steel Scales but also heal itself for the amount of HP the slime have. Blue Mages can learn that spell. - Split : At around 68% HP, the boss will split into two with both having halved HP and damage. Both bosses will gain Steel Scales over time.
- Merge : After the split, Caduceus will merge with its duplicate if they get too close to one another, merging their HP and rapidly gain Steel Scales
- Enrage : Caduceus will rapidly gain Steel Scales when the other Caduceus is killed. Burn them both down at around the same time.
Strategy
Spread out. Assign players to spawn slime. DPS the slime down to around 20% before letting. Bring the slime towards the boss from its side. Splitting the boss when it has no stacks is greatly preferred
On split, take your party and split in to 2 light parties and burn your respective bosses. Continue to drag slimes to the boss during this phase to prevent the tanks from getting overwhelmed. Split DPS equally and make sure both of them are away from each other.

Dialogue
Cutscene
Alisaie: The scars left by the Calamity... Alisaie: I can scarce breathe for the surfeit of aether. Alisaie: Tell me, have you ever seen corrupted crystals such as these? Alisaie: Such crystals manifested across the realm when the course of the great river of aether was irrevocably altered five years ago. Alisaie: Behold, one of the objects that caused that alteration: a fragment of the lesser moon, Dalamud. Alisaie: Ancient Allag created Dalamud—or Meteor, to use the Garlean name—to serve as a celestial prison for Bahamut. Alisaie: Its fall inflicted grievous wounds upon the land—wounds that have yet to heal, as is evident from the corrupted crystals. Alisaie: Amazing... Dalamud's internal defenses still function in spite of everything—a testament to the ingenuity of the Allagans. Alisaie: The Garleans seek to appropriate their advanced technology, I am certain of it. Alisaie: We are about to come face-to-face with secrets that have long lain buried within the sands of time. Alisaie: Great dangers may lie beyond, but we have come too far to turn back. The truth of the Calamity is within reach.
Cutscene 2
Alisaie: <gasp> Gods preserve... Alisaie: Dark wings that would engulf the very heavens... Alisaie: These could only belong to Bahamut, the primal who laid Eorzea to waste five years ago. Alisaie: At Carteneau, my grandfather sought to imprison Bahamut anew by invoking the power of the Twelve. Alisaie: Alas, the dreadwyrm proved too powerful, and he soon broke free of his confines. Alisaie: Yet instead of resuming the destruction he had begun, Bahamut vanished. Whither to, no one knew...until this day. Alisaie: But I do not understand... If Bahamut is truly a primal, how is it that he retains his physical form? Alisaie: Did Grandfather defeat him? Or is there some other explanation? Alisaie: We must press on if we are to learn the truth.
