[@Willy Vereb] OK, so I decided to cap technology level at antimatter after all. I'll give you the anti-star since you ditched the relic option despite me wondering just how catastrophic would solar wind be on contact with the atmosphere of the planet. The tech... there are so many little hitches that by the time they're all ironed out it's going to look nothing like the original. I want everything above antimatter to be the [i]occasional irregularity[/i], in a sense that you got it to work, you are not exactly sure how and if your theories are even correct and you are drawing blanks on how to make them better. I'll give you using gravity fields to generate thrust, inertial dampening and gravity for crew; shielding and weapons not that much. I am not banning more advanced tech, but I want to have technological progress on that level to happen IC, whether with relic assistance if you're lucky or on your own. From what I read on the sites you linked, it seems like the biology, mentality, gov, history, ... of the empire will be fine once the fact that they didn't meet any aliens yet is taken into account. If you feel like those are too drastic changes I ask of you, then I'd bid you to reconsider using this nation for this RP. I am adamant at everyone starting at more or less the same conditions - if you want to conquer others with superior technology then you're going to have to invent it, all you can do now is lay the ground work for the rapid progress which I think your people have in check.
