Myrrine is the protagonist's mother in Assassin's Creed Odyssey. She is the mother of Kassandra or Alexios, the player-selected descendant of King Leonidas I.
Myrrine is central to the game's family storyline. After events involving Sparta and Mount Taygetos, she leaves her former life and later becomes connected with the island of Naxos. The search for family members forms one of Odyssey's main narrative threads and takes the protagonist across the Greek world.
The player can choose Kassandra or Alexios as the playable character, but the family relationship with Myrrine remains part of the story. Aspasia is an Athenian political figure and an important character, while Phoibe is a young ally. Olympias is the mother of Alexander the Great and is not the protagonist's mother in Odyssey.
