With work on the Enterprise nearing completion, Alphinaud bids you tell Y'shtola to make ready for departure.
You find Y'shtola in uncommonly good cheer -- in stark contrast to Estinien, who seems to take her positivity as a personal affront. As you look on bemused, a tense exchange ensues in which Y'shtola warns Estinien that the Eye will consume him given the slightest opportunity. Of course, the dragoon is having none of it. As he strides off, Urianger arrives bearing a gift of white auracite, found among Moenbryda's last effects, thus rounding off your unexpectedly eventful errand. Rejoin Alphinaud at the airship landing.
You inform Alphinaud of the party's readiness to set forth. The time has come to journey to the stage of the final battle -- Azys Lla.
You take your place aboard the new and improved Enterprise Excelsior, and after a journey of what feels like mere moments, gain sight of Azys Lla. As promised, the newly installed aetheric ram makes short work of the Allagan barrier, but you have no time to celebrate, as an imperial battleship appears in your wake and opens fire. Hopelessly outmatched, you prepare for the end, only to spy Ysayle riding to the rescue upon Hraesvelgr's back. Transforming into Shiva, she engages the enemy battleship single-handed, and succeeds in incapacitating it at the cost of her own life.
When you subsequently arrive in Azys Lla, you say a silent prayer for the allies who have paid the ultimate price that you might fight on.
All are determined that Ysayle's sacrifice should not be in vain. Join your companions at the dome-like structure, and ask Cid for further instructions.
Cid declares the area safe, and calls a meeting to discuss the next step.
In order to undertake the next main scenario quest, you must first complete the quest “My Little Chocobo (Maelstrom/Twin Adder/Immortal Flames).”
You may accept the quest “My Little Chocobo (Maelstrom/Twin Adder/Immortal Flames)” by speaking with R'ashaht Rhiki at Maelstrom Command/Vorsaile Heuloix at the Adders' Nest/Commander Swift at the Hall of Flames.
Until but recently, the Ishgardians had kept their doors firmly shut to outsiders.
But thanks to you, we have found in them stout allies, with whom we may fight to secure the future of the realm. Truly, you are the beacon of hope towards which all men are drawn.
'Twas not mine intent to make light of your struggle. If I have given offense, then I apologize. But if I may speak freely, you would do well to be wary of the Eye. Even now, it burns with insatiable hatred, watching unblinking for a sign of weakness. Should you falter for so much as a moment, it will surely consume you.
To mine amazement, it lay hid amongst Moenbryda's last effects. 'Twas but my blind chance, or providence, that I did hap to spy it. Let no man claim that my late friend e'er erred for lack of foresight.
In the place whither thou goest, servants of Darkness do lie in wait. Pray give unto me thy pledge that thou wilt strike them down and avenge our fallen comrade.
That which man thinketh a trifle in the having, he mourneth as a treasure in the losing. A tired platitude, but one which shall haunt me unto my dying day.
O goddess born of mine own hopes and dreams. For the last time, I beseech you!
Fill this vessel with your light! Still the hatred within our hearts and bless us with eternal grace!
[Ysayle transforms into Shiva while falling. She encases herself in a massive ice missile and strikes the imperial airship but is then struck several times by fire.]
Twelve grant her mercy... Brief though our time together was, Ysayle was a true friend—a gentle soul who fought for her beliefs. She...she would have made a fine Scion.
