In Assassin’s Creed Odyssey you play a stone cold bad ass. Kassandra (because let’s be real: you’re playing as Kassandra) walks without fear through Greece. Any person that steps to Kassandra, that person is getting a kicking. This confidence may account for Kassandra’s healthy scepticism of some of the more bizarre aspects of Ancient Greek religion (e.g. is that lady really an Oracle delivering genuine prophecy, or is she perhaps high out of her mind and on the take from shady characters?).
But in keeping with Origins offering a sprawling open world experience, Ancient Greece is populated by normal Grecians, who have to earn a living though more mundane methods than being an unstoppable mercenary. There are loads of them doing normal jobs in every town, getting bored, going home, stopping for a scratch when they’re tired. Ancient Greece is alive (and kicking, haha).
