When the senary moon did wane, there sounded a blood-curdling roar. A new primal has roused, the portents gave us to believe, and one whose identity yet lieth beyond our ken. By thy hand, three primals have since been vanquished. As each returned to the aether, 'twas observed that tremors foreshadowing this fourth grew in strength and frequency both. The being doth quicken, and in time it shall become a scourge upon the land. Yet even as we pondered a course of action, a benevolent soul did arise, one who would forestall this threat. Though she be tender in years, she is true of heart and steadfast of resolve. She would solicit thine aid, if thou art willing to proffer it. Lest thou wonder, this maiden is of our order. Thus did the Antecedent straightways consent that thou shouldst assist her howsoever thou mayest. As soon as thou art able, hie thee to Wineport, where thy petitioner doth await thee even now. Thou shalt for a certainty find her visage strikingly familiar.
You travel to Wineport.
It has been a while, adventurer. As I recall, my brother Alphinaud took the liberty of introducing us when first--and last--we met. But for the sake of propriety... Alisaie Leveilleur. I thank you for coming. I have heard much and more of your exploits. By your hand, the Black Wolf is slain, and his Ultima Weapon destroyed. You are possessed of great strength and courave, that much is plain. I shall have need of one such as you if I am to see my mission through to its conclusion.
As you may be aware, the violence of Dalamud's fall changed not only the face of the realm, but also the base of the realm. Specifically, it played havoc with the aetheric currents, creating vast confluences of aether below the surface. Among other phenomena, this led to the formation of subterranean caverns at key points of stress. One such cavern lies beneath Castrum Occidens, and extends to only the gods know where. Despite appearances, Castrum Occidens is as much a research facility as it is a fortress. Gaius van Baelsar chose the site for no other reason than to probe the caverns without interference. As you went about vanquishing the returned primals, I observed a repeating wave pattern in the aether, corresponding exactly to the dates on which you reported to have felled Ifrit, Titan and Garuda. Upon closer examination, it became clear that these unique waveforms emanated from deep beneath the aforementioned stronghold. Crucially, I recorded the same pattern during the recent celebrations, and have since been given to understand that this phenomenon bears a disquieting similarity to one observed shortly prior to the Calamity.
Five years ago, my grandfather invoked the power of the Twelve that he might contain Bahamut. Alas, his efforts failed, and he vanished, together with his foe. I would know the truth of what transpired that day--of Grandfather's fate, and of the metamorphosis that swept across the land. In casting light upon these mysteries, we will find a way to cure what ails this world. It is my belief that the answers I seek lie hid within the depths of the cavern. I would have you accompany me on an expedition to find them, PLAYERNAME. If truth be told, I am not wont to rely upon others, and have thus far handled matters alone. Yet I am not blind to my limitations. Unescorted, I cannot hope to succeed in this endeavor. I swore that I would find a way to restore peace to Eorzea. If you desire the selfsame, then aid me, as you aided my brother and the Scions.
I am in your debt. You are a man/woman of action, and I sense that we will accomplish much together. But let us not waste any more time. As I mentioned, Castrum Occidens straddles the cavern I wish to explore. If I am to have a hope of reaching it alive, I will need you to infiltrate the stronghold first and locate a path into the depths. Once you have done so, pray report your success to Storm Private J'brohka. You may consider her my assistant here in Wineport. I have every faith that you will not fail me. Twelve speed your way, PLAYERNAME.
You fight your way through Castrum Occidens, discover the Exploratory Site Gate, and head back to report your find.
I've been expecting you, PLAYERNAME. By your coming, I take it you have successfully located the cavern entrance inside Castrum Occidens? ...So that's where it's to be found! Marvelous! Oh, but allow me to properly introduce myself. J'brohka is my name, and it is my honor to serve Lady Alisaie. Though for reasons of convenience, at present I also serve the Maelstrom. This uniform accords me certain privileges, you see--in particular, ready access to the Maelstrom's regional scouting reports. They provide a wealth of local knowledge, including information on secret passages. Once your preparations are in order, let me know, and I will see you to the cavern entrance together with Lady Alisaie. Though I don't doubt your abilities, none can say what dangers lurk beneath Castrum Occidens. For my lady's sake as well as your own, please spare neither preparation nor caution. Pray choose your companions well.
