Upon entering Ambervale, Marche meets with Cid in the courtyard of a palace. Cid says that in ancient times, a king built it as "a prayer for peace," mentioning that it's like a chapel rather than a palace. It's an oddly peaceful and beautiful location for The Very Definitely Final Dungeon.
They then find Babus lying on the ground, unresponsive to Marche's questions. Llednar then arrives and informs them that he's just unconscious. After being told to stand aside, Llednar reiterates that he's not going to let them by, but Marche insists on going through.
Cid then unleashes the antilaw he had Ezel make, and removes the "Fortune" antilaw protecting Llednar. Llednar, his stoic facade breaking for a moment, tells Marche that it "reeks of foul play," and implies that he'd kill Marche if Cid weren't around, before summoning some minions.
The battle music is one of the more exciting tracks, "Unavoidable Destiny," and is one of the main ones for a quasi-boss battle apart from "The Road We Both Aim For."
Llednar's minions are fairly strong damage dealers (an Illusionist, a Ninja, an Assassin, a Gunner and an Alchemist), and you're outnumbered, since Babus' unconscious body counts as one of your people. You thus have to defeat six opponents with four people.
Fortunately, you only need to kill Llednar, although in my most recent playthrough, I was also able to kill his minions.
During the battle, another conversation ensues, with Llednar telling Marche to get out, and Marche having a hard time believing that Llednar's any part of Mewt. Llednar refuses to tell Marche who's giving him his orders, planning on killing him.
Once Llednar's defeated he protests his fate, turns to stone and crumbles to dust.
Babus wakes up, and is upset to hear that Mewt isn't with Marche or Cid, and has most likely gone inside. He tries to go in, but collapses from his wounds, and, in spite of insisting otherwise, Cid convinces him to stay behind, apologizing for being too late to help him, and Babus hesitantly complies. The large gate to the palace opens and Marche and Cid walk inside.
Inside, Remedi is waiting, in a wide open room with a large statue at the back that has an open right hand with the palm up. She's noticed Llednar's passing, and laments that Mewt has lost another friend, but Marche says that nothing he's lost in this world is real. Remedi says that the world is an illusion, but believes that even Marche has not yet accepted that.
Remedi calls out to Mewt, who appears in the palm of the statue's hand, and asks him what he wants. He still wants to stay with her, and vanishes before he can say anything else, or anyone can say anything to him.
Remedi tells Marche and Cid to leave, before turning into an armored, scythe-wielding warrior, and summoning clones of Famfrit and Adrammelech. A special battle music, "Surpassing The Wall", begins to play as the first stage of the Final Battle begins. She says she exists because the world is still wanted. Marche, however, says that "This world is a dream, and I'm done with dreaming!"
Remedi is not especially fast, nor does she have any abilities besides a physical attack, but that attack hits quite hard. It would seem like a simple thing to defeat her, but Remedi is accompanied by clones of Famfrit and Adrammelech. The former seems to go in close and use Breath of God as an area of effect attack, while the latter often walks along the side and snipes your units with a fire stream attack. Both have exorbitantly large amounts of health, so defeating them is not practical.
Once Remedi's defeated, she falls to her knees and weakly calls out to Mewt, and Marche and Cid do so as well once Mewt reappears in the statue's hand. Mewt says that a part of him understands that the world should go back to normal, but he still wants to stay there.
In response, Remedi assumes her One-Winged Angel form and turns into a blue fairy-like creature that seems to have a crystalline lower body, while summoning two clones of Mateus. Cid says that Remedi is no longer his wife or the queen, but the composite manifestation of everyone's desires. It's clear that there's one more stage to this final battle, making it the first and only three-part mission.
The final battle music, "Incarnation," plays, a suitably epic track for the final battle. Oddly enough, you have seven units in this battle, but since there are two down already, means you can only place five. I have to wonder if Mewt is counted as a unit.
One of Remedi's abilities in the "Li-Grim" job, rather than her "Battle Queen" job (It's somewhat surprising how many enemies get custom jobs, even relatively ordinary monsters; for example, Llednar is a "Biskmatar," while the Totema clones are "Dephs"), is Descent, the ability to summon a random Totema, at no JP cost, which is as cheap and deadly as it sounds]. If she decides to use it, you had better hope she gets Ultima or Exodus, which reduce your casters' mana to 0, instead of the other three, which will likely lead to a Total Party Kill.
Remedi can also use other abilities, including the ability to randomly shift the laws, Omega, and Alpha, which is apparently an even more powerful version of Omega. Those are quite powerful, but they don't imperil you the same way Descent does.
Remedi also has two clones of Mateus, whom you will be hard-pressed to defeat before her, so you should focus your attention on her.
Once Remedi's down to half health, regardless of whose turn it is, Marche calls out to Mewt, saying he can't triumph by himself. Mewt makes what vaguely sounds like an expression of his desire to go home, before his voice falls silent again.
Once Remedi's defeated at long last, Mewt wakes up, and calls out to his mother as Remedi vanishes, before he himself vanishes as well.
