Assassin's Creed: Odyssey's hidden Historical Locations map is stuffed with Ancient Greek lore

History is my favorite part of Assassin's Creed. Years ago I used to read through all the historical database entries, getting context about historical figures and landmarks in Florence, Rome, colonial Boston, and more. And I spent hours in Assassin's Creed: Origins's Discovery Tour earlier this year, admiring how much detail Ubisoft put into recreating Ptolemaic Egypt from both primary and secondary sources.
