Slightly unrelated to Collide: Was it ever explained how the Condensce got to Earth? Like, yeah she flew in her ship but the trolls were in an entirely different universe than the humans, and I'm pretty sure the Incipisphere is in an entirely different dimension, so how is she just showing up in all these places when everyone else has some kind of portal (normally the initial warp into P-Space or a Skaia portal) to explain how they got there?

Really if you can navigate the Furthest Ring you can get anywhere.
