This is Part 1 of the canonical playthrough . Finish these nine chapters before Legacy of the First Blade. You can hunt Cultists and side quests in the same regions as you go. Do not start Korfu.
Kassandra is the canon protagonist. The family members swap names if you play as Alexios (you are then hunting Kassandra as Deimos). The choices below are the same either way.
The family arc is one of three base-game stories. Completing Chapter 9 does not end the game. It ends the bloodline plot and unlocks the Sparta dinner if you kept everyone alive.
The six choices that make the dinner happen
Miss any one of these and someone is missing from the house in Sparta.
- Chapter 2 — The Wolf of Sparta (Megaris). Do not kill Nikolaos.
- Chapter 6 — reunion with Myrrine (Naxos). Tell her you will try to save Deimos. (“We’ll get him/her back.” Do not say they are beyond saving.)
- Chapter 7 — The Last Fight of Aristalos (Boeotia). When you find Nikolaos again, convince him to go to Stentor.
- Chapter 7 — The Conqueror (Boeotia). Do not kill Stentor. If Nikolaos intervenes, you never have to duel him.
- Chapter 8 — The Battle of Pylos. Start pulling Deimos out of the Cult. Do not treat them as an enemy you are happy to bury.
- Chapter 9 — Where It All Began (Mount Taygetos). Refuse to fight Deimos. Offer the spear. Say you do not want to fight.
There is an earlier tone check in Chapter 3 inside the Cult’s cave in Phokis (The Serpent’s Lair). Do not bait or mock Deimos. You cannot “fail” the ending in that scene alone, but you can poison the later Pylos and Taygetos conversations.
Chapter map
Chapters 1–2 — Kephallonia and Megaris
Markos’s debts, Phoibe, Barnabas, the Adrestia, then the mercenary contract that dumps you into the Peloponnesian War. In Megaris you fight for Sparta under Nikolaos, the Wolf of Sparta — your stepfather, not your blood father.
Side note: play Blood Fever on Kephallonia before you sail. It is easy to outlevel and miss, and it is one of the island’s best character beats.
Chapter 3 — Phokis
Elpenor, the Oracle at Delphi, and The Serpent’s Lair. This is where the Cult of Kosmos board unlocks. You meet Deimos as the Cult’s weapon. Treat the meeting as family, not as a boss fight.
After this chapter, keep the Cult investigation open in the pause menu. Clues drop as you travel. You do not need to finish the Cult before Chapter 9.
Chapters 4–5 — Attika, then the hunt for Myrrine
Athens introduces Perikles, Aspasia, Sokrates, Alkibiades, and Hippokrates. Then the story splits you across Korinthia (Anthousa and the Monger), Argolis (Chrysis, the Sanctuary of Asklepios), and Keos (Xenia). Each region is a lead on Myrrine, who is using the alias Phoenix.
The Monger and Chrysis are also Cultists. Killing them here feeds the Cult guide without extra backtracking.
Chapter 6 — Athens burns, Naxos, Thera
You return to a plague-struck Athens. Perikles falls. Phoibe is murdered. Aspasia flees with you to Naxos. Myrrine is the island’s ruler. Help her finish the war with Paros (United Front), then take A Family’s Legacy to the island of Thera.
Thera is the door to Atlantis and Pythagoras. That quest is still part of the family story, but it opens the beast hunts . You can postpone the four bosses; do not postpone meeting Pythagoras.
Required line on Naxos: promise Myrrine you will save Deimos.
Chapter 7 — Sparta, Elis, Boeotia
Myrrine takes you home. Sparta’s kings, Pausanias and Archidamos, are playing the Cult’s game. The Olympic subplot in Elis and Brasidas’s war in Messenia/Boeotia sit on this chapter. The ending-critical scenes are Nikolaos in The Last Fight of Aristalos and Stentor in The Conqueror. Send Nikolaos to his adopted son.
Chapter 8 — Pylos, prison, Amphipolis
Kleon replaces Perikles as Athens’s strongman. The Battle of Pylos is where you can reach Deimos as a sibling instead of as a demigod. Brasidas dies at Amphipolis. That death is scripted; you cannot save him. You can still save Deimos.
Chapter 9 — Mount Taygetos
Where It All Began returns the family to the mountain where Deimos was thrown as a child. If the five earlier choices are clean, you get the option not to fight. Deimos takes the spear. Myrrine holds them. The next scene is dinner in the Spartan house — Kassandra (or Alexios), Deimos, Myrrine, Nikolaos, and Stentor.
That dinner is the canonical family ending. The achievement is Odyssey’s End. The game is not over.
What to do the same day you finish Chapter 9
- If the Cult board still has names, move to Part 3 . Deimos is resolved here; the Ghost is not.
- If Thera is open and you are near max level, start Part 4 .
- If both of those are done, sail north for Legacy of the First Blade .
Do not sail to Sami for A Great Escape yet.
