Aaron Berger other stuff you asked about:

* Yeah, I backed the Emissary campaign book. I have no idea when I’d run it but I’ll have it, you bet.

And the differences between the planets, I’m just totally making that shit up. I mean there were hundreds of years, I think, post Portal Wars pre arrival of the Zenith where there was no space travel, IIRC. So yeah, I think the planets surely diverged during that time.

One of my favorite bits about the setting is how fast things have changed since the Zenith arrived. It’s only been 60 years! But now there are 10 factions, several religions, an all-encompassing megacorp, and a pseudo-Internet. Which seems very much like a story of the late 20th century.
