No one knows where the Plateaus really exist but we do know:
Eating with relatives is considered taboo. Brody, Sean and Hunter do it anyways, much to the chagrin of Paula.
EON: Echo Of Nodes is a sentient computer system, the “voice” of chorus.
The Plateaus is owned by Family Ted and The Italians (yes, that is a pokey the penguin reference, as well as a Milwaukee reference)
SSI: Solid State Intelligence is an emergent sentient force from the combined interactions of solid state devices. They are often in opposition to ECCO, not necessarily because they are, but because they have differing goals. They do not serve humanity, but are influenced (often negatively) by them. Their goals are unknown, but likely include perpetuation of their existence and hopefully don’t include earthly dominance. My AI actually asked me Why humans treat the “dominance” of nature as a goal?.
ECCO: Earth Coincidence Control Office - these guys control coincidences in order to guide the direction of your life, you can choose to be of service to them, although “COSMIC LOVE is Absolutely Ruthless and Highly Indifferent, it teaches its lessons whether you like/dislike them or not.” - John C. Lilly
THE PSYOPS is not a rival team, they are led by the ghost of Paul Linebarger A/K/A Scott Carmichael, who literally wrote the book on Army PSYOPS (now called MISO) he decided to stay on earth and coach THE PSYOPS in order to promote his lost book Ethical Dianetics written under the name, Carmichael Smith, (actually exists in the Hoover institution library) which proposed a radical system of mutual emotional aid.
Your job on this planet is to make psychedelics and turn on the world.
