But yeah, there's some potential for plenty of stories with what Kassandra was up to during all the other games, like her relationship with both factions, or was she possibly manipulating both?
Interesting this is there's also possibly another immortal in AC: Reda the merchant who appears in Origins and Valhalla. Maybe another kid of Kassandra's, except maybe he somehow inherited her immortality somehow? Or a similar Isu artifact?
