Following the battle against Ultima - and all the craziness that followed - Clive will wind up, one last time back in the Hideaway. Trek over to the Mess and report in to Otto, which will bring the whole crew together to hear Clive's story. Everyone will split up again after the cut scene, with no answers to their problems.
Head to the Boarding Deck and speak to Joshua, which leads to a lengthy cut scene. Once that is done, head to Clive's Chambers and check on the balcony near his Reading Desk. Jill is standing out here, and she'll another scene with Clive.
Speaking to Jill will trigger the end game of Final Fantasy XVI. If you check the world map a marker will appear for Origin, the enormous crystal where you're meant to face off against Ultima. This also triggers the last of the game's side content, and since going to Origin is a one-way trip you might want to get all of this stuff out of the way. There's a lot.
- Eight new side quests will appear in the Hideaway: An Inconvenient Truth, More Than Words, Trial and Error, Nobody's Tool, Where There's a Will, Three's Company, Litany of Errors, and Aiming High. Complete Where There's a Will and you'll unlock another quest, Priceless, and complete An Inconvenient Truth to unlock A Tail to Tell.
- You'll also find side quests in several places throughout the world: Under New Management II (Northreach), Lines in the Sand II (Dalimil Inn), and Duty Undying II (Tabor).
- Complete the new quests that pop up and you can unlock the last few Notorious Marks: Behemoth King, Kuza Beast, Gizamaluk, Prince of Death, and Knight of the Splendent Heart.
- If you didn't bother doing much of the optional stuff you can forge the Circle of Heaven +1 and the Sun Bracelets +1 at the Black Hammer. If you have been doing side quests, however, there are better items available.
- Assuming you haven't tackled them already, there are seven Chronoliths spread throughout the world that you can activate and challenge for some extra goodies. We'll explore them in another guide.
