I object to the inclusion of a Oceania House, I find it far more likely that the Australians, Canadians, South Africans (Yeah I said it), New Zealanders and other Imperial territories would have been included in the Bretonia simply because they were Imperial territories. I don't understand the very early history of the FL universe but I imagine it would have been fairly similar up until 1945 at which point the universes 'diverge'.
I can also make the case that including another house will lead to dead systems and more system creation for those whose time is already being used on the current systems (given there is a patch delay, I find this a relevant point to make). And why Australia? Why not Brazil? or India? I also find it remarkably hard to believe that Australia would just conjure up a sleeper ship of its own all on its own, does it not make a little more sense to assume that the 5 sleeper ships were carrying more than just their respective peoples? (This in turn risks turning us down a rather unhappy geo-political conversation which we are going to ignore but is also another point against another house).
I'm aware this is flood, I'm aware it probably isn't a serious thread and I don't care.
