In PS gaidin, the homeworld of some of the algolians was a planet called Copal. It may be a mistranslation, or something like that. I do believe it was Rune that sealed the dark falz away. Maybe one escaped from the edge before they destroyed PD, and the rest of the heros were dead, but Rune's memories of everything were stored with Lutz's in the telepathy ball... so it was the next incarnation of Lutz that sealed it away on a ship, and took it to another planet. PSO could be set far off into the future, so that there's no memory of the Algol star system, and the adventures there, but PSO must come after PS2 or PS4, since the first newman appears in PS2, and the next is in PS4. I'd assume that it must be after PS4, since at the time of PS4, Rika was the only newman. It would take a bit for the newman genetics to become a race of people in and of itself. Or else Sonic team read less into this then me, and just put in newmans because they had been in previous games, and they wanted to keep up tradition. I don't know, man. Lots of shit to look into... doesn't make a whole lot of sense.
