I'm starting to think that hiveswap Alternia is not the same one from chapter 4 hivebent. I'm saying its not the same planet, but the beta trolls created the universe that the beta kids live in and are not physically in that universe. I guess I HC that this is the beta kids alternia with none of the beta trolls showing up, and the one that Lord English razes in homestuck.

That’s. Not how it works, Universes aren’t identical, there’s not an ‘Alternia’ on the Red Universe, it’s on the Blue, and they’re two entirely different instances of a Universe. There’s no Trolls on the Red Universe as far as we know.
