Yes my dear Fetzen

You're right, but I just want some visibility in our posts

My dear Blacky

:p Yes, I say that imperial claims the Belt.
Explanations :
1 - Victoria is their land, and remember, books were writen before some major astronomical disvoveries.
2 - Imperial colonizing belt ( no more telluric planets weren't free ), at Ancient's time, their knowledge about asteroids was perfect, so we can easily conclude that's Victoria is the biggest planetoid of the belt.
3 - Even if Cybertro is inplanted in space ( like the C-Base ), Imperial, with its mighties clans, or special forces, will never abandonned its superiotity to this "cyberdegenerated bastards and minions of the last darkness", hum sorry

So, I will ask your sources about """Cybertronic acquired some bigger asteroids, in particular Ceres and Dembowska. They also colonized the asteroid fields of Jupiter.""" But for Jupiter or rings, i'm agree.
4 - Population of Cybertronic is very too tiny versus Imperial ones to claim openly suprematy ( i've calculated human population too, like planet's ones, with demographic data like MC 2th ed for Luna, and my results was compatible to MC 2th ed ), like MIp is ridiculous comparated to Capitol

( and Capitol considers asteroids belt secondary : capitolian have a land, Mars :p )
5 - """Then bigger asteroids where moved together, connected to each other and so many small worlds have been formed. So I would say, that Cybertronic is main habitant of the asteroid fields."""
Cybertronic's age : approx. 140 years, Imperial so much more, I think it's not an argument.

And remember, Imp was truely more powerful before its internal war.
6 - to continue about 5th point. Terraformations were specificities about the Ancients, I can't imagine no ones create atmospheres or assembling very big rocks after Symetry's coming. It would suppose presence of Thermonuclear reactors, fusion propelled engineries, over mega computorized technologies... It's totally out of our "steam-retro-dark-older-archaic-strange-gothic-horror" universe
That's my first opposite points.
For space travels, in my play system, astronav rolls will determinate duration's travel. If you are very good, with perfect roll, your travel time will be strongly shorted, or one a fumble, it will be twice or worst..
In my definition, Astronav competence is the knowledge of space maps and harrisson tunnels, and calculation about effects of this hole and their stability.
