This is Part 6 of the canonical playthrough and the last story beat on the Greek map.
Ubisoft shipped Those Who Are Treasured as a free crossover with Valhalla. It is written as an epilogue. The game will still let you pick it up after Chapter 1 in Megaris. Ignore that. The quest text and the later Valhalla meeting on Skye both assume Kassandra has already become the Keeper of the Staff.
Checklist before you sail
Do not start Korfu until all of this is true:
- Family Chapter 9 is done (Sparta dinner if you are going for the full house).
- Cult of Kosmos is wiped, including A Fresh Start and the Ghost.
- Gates of Atlantis are sealed.
- Legacy of the First Blade is finished, epilogue included.
- Fate of Atlantis is finished, Staff accepted.
Lost Tales of Greece can wait forever. Korfu should not.
How it actually starts
- Go to Sami, the port on Kephallonia — the island you left in Chapter 1.
- Find the quest giver and start A Great Escape (some menus label it The Great Escape).
- That loads Those Who Are Treasured.
Barnabas and Herodotos are behind the invitation. They are sending you on a vacation because you have been a weapon for too long. Korfu is the holiday that turns into a Piece of Eden chase.
What the epilogue is doing
You are back with the two people who made the Adrestia a home. The plot involves a treasure, an Isu artifact, and a reminder that the Staff’s job is not over. The important character work is smaller than the set pieces:
- The Spear of Leonidas runs out of miracles. The broken gift from Leonidas stops being a Precursor crutch. That only lands if you have lived with the spear for the whole saga.
- You say a real goodbye to the crew instead of wandering off mid-conquest.
- The Eagle Bearer steps onto the long walk that ends in the modern day, when Layla takes the Staff on Thera. Valhalla’s A Fated Encounter then meets Kassandra on the Isle of Skye — another reason to have played her, and to have played this last.
This is Odyssey’s ending in the sense that matters. There is no credit roll after Chapter 9. There is this.
After Korfu
You can still roam Greece, finish trophies, and replay conquests. Narratively the mercenary story is closed. If you are planning more guides on this save, they are systems pieces (builds, ship, New Game+) rather than story parts.
This series stops here on purpose.
