The Porta Decumana Image.png
Making your way through the Praetorium, you sweep aside wave after wave of defenders before finally coming face-to-face with Gaius van Baelsar himself. Unable to overcome you by his own hands, the Black Wolf takes control of the Ultima Weapon and sets upon you once more. Do what you have come to do, and see that the magitek monstrosity never threatens Eorzea again.

Edit The Porta Decumana's Dialogue
Player7 Icon.png Voiced cutscene start.
Bear witness to the true power of the Ultima Weapon!
Player7 Icon.png Voiced cutscene end.
The Ultima Weapon has partaken of the power of eikons! None can stand against it!

Kneel to the might below!

The land itself is mine to wield!

Be entombed in earth!
Hear... Feel... Think...
Thy foe is Darkness clad in steel. If thou wouldst triumph, thou must look to the Light.
Titan's essence...torn from the Ultima Weapon!?

No matter─it still harbors the might of other eikons!

Yield to the storm!

The wind is at my beck and call!

Naught can pierce the raging tempest!
Once more, crystal bearer. Look to the Light to vanquish the Darkness.
Garuda's as well!? Impossible!

But the Ultima Weapon is not spent of eikon power yet!

Succumb to the flames!

So this is the strength of the eikon-slayer...

Very well, let us see how you fare when the Ultima Weapon's power inhibitor is disengaged!

Naught will remain of you but ash!
Yield not to the Darkness, my child. Pray to the Crystal with all thy being.
No! are you doing this!?
Player7 Icon.png Voiced cutscene start.
But the Ultima Weapon is all-powerful! Why does my enemy still stand!?
Can her strength truly be so great?
It is the blessing of Light that confounds you.
Your foe acts under the protection of the Crystal he bears.
So, this is what empowers her.
Beyond mortal limits.

If you are to prevail, the hammer of Darkness must needs be brought to bear upon the shield of Light.

And so it shall, for the Ultima Weapon is host to a power of which you are as yet ignorant.
Speak plainly, Ascian.
The Heart of Sabik. It is the Weapon's core─an enigma whose surface even the vaunted scholars of ancient Allag failed to scratch.
The magic within has lain dormant for eons.
Of what magic do you speak?
A spell without parallel. Ultima.
I sought the life force of the primals for no other reason but to quicken the core. For the true power of the Ultima Weapon lies within its now-beating Heart!
Lahabrea... What have you done?
No more than was necessary...for my god to be reborn.
Damn you, Ascian!
The hour is at hand! Behold but a sliver of my god's power!

And from the deepest pit of the seven hells to the very pinnacle of the heavens, the world shall tremble! Unleash Ultima!

Such devastation... This was not my intention...
Oh, seems the task of keeping Your champion alive has exhausted what strength You had left.

Van Baelsar... Your enemy's shield is broken.

The rest I leave to you.
We will speak later, Ascian.

But first, I must deal with you. The question of who is mightier remains!

Come, adventurer! Let us find the answer together!
Player7 Icon.png Voiced cutscene end.
We settle this once and for all!

I need not the power of eikons to defeat you! Gaze upon true power!

This is most...unexpected. You are possessed of great might, this I will allow.

Yet yours is not the might of a ruler! Such is the difference between us─a difference that will assure my victory!

U-Ultima!? Curse you, Ascian!

How much destruction must be wreaked before you are sated!?
I have not the shield thee again...
Permit not the manifestation of that vile magick...lest Darkness prevail!
Player7 Icon.png Voiced cutscene start.
No... No, no, NO! Uh!

Heed me... The subjects of a weak ruler must needs look to a higher power for providence...and their dependence comes at a cost to the realm.

The misguided elevate the frail... And the frail lead the people astray.

Unless a man of power wrests control...the cycle will never be broken.

You... You of all people must see the truth in this. You who have the strength to rule...
