- The Achaean civilisation coexisted with Saqqara and Eastern Landmass Civilisation.
- It wasn't a unified country. Instead, it consisted of a bunch of independent city-cities, and their colonies, which never managed to unite, but still considered themselves the same people.
- The Ebissian Sea used to be smaller, containing more isles and islands, particularly bigger ones. Many of them sunk into the waters when the civilisation fell. Some of the remnants of this catastrophic collapse can be seen in features such as the Broken Beach, the Shattered Shore, and the Garland; the latter used to be a land bridge connecting the Watchers' Island to Eastern Landmass™, and held the "Atlantis"-like Achaean city.
- Apart from ancient Humans, Cyclopes, Minotaurs, Centaurs, and many other Greek mythological creatures that made it to Pathfinder were also a part of this society.
- Achaeans are similar in vibes to the Azlanti of Golarion, who became Azarketi. Perhaps in the New World, these Humans turned into Merfolk (and Cecaelias?) instead, and their descendants still live today in the oceans.
- Veshta and her Unknown sisters, who used to plague the Unseen Village on the Verge, assumed illusory forms of Merfolk, and Veshta herself acted as Bernadette, a Cacaelia oracle of Aburayan Springs.
- The hydrothermal forge "Chained Reaction", in the Drowned Quarter of Cynosure, used to be an Achaean, then an Elven ruin, before it was claimed by Kǂalvis.
- Unknown the Many-voiced used to lair inside a Cyclopean ruin of Achaeans within the Garland.
