“good morning, starshine
the earth says hello
you twinkle above us
we twinkle below”
This is a neat concept for the sci-fi side of the CVU, the Dyson Sphere is basically a giant construct (understatement) that covers our solar system and it serves a vast number of purposes. It can be living space for human or alien colonies, it can be weaponized for interstellar defense or used as a spatial transit point from this solar system to the next one. This would be a great place as the meeting point for all space related characters/races in the CVU, where space cops can post their base and where cosmic enemies can be detected before entering the vicinity of earth. I am just offering a concept, which will handled by those with great sci fi characters (we do have a lot of those here). The earth may be cluttered with satellites but a dyson sphere can be accommodated to fit all (or a lot of those). Characters can have their spaces or base within the Sphere too.
List of characters that have bases in the sphere
List of events that have taken place in the sphere
this is just a general idea but please do have fun.
