I think a great idea would be to have some futuristic invaders of a generic faction land/crash on Medivo
Well, I did introduced these small
'space' agents a.k.a. Immortals, and they had to sacrifice an entire planet to get them on Medivo. So while it is possible to get your troops there, it's only accessible via dark arts and horrendous amount of deaths. And seriously, as a galaktik conqueror, would you give up more (much, much more) to gain less? (ie: wipe out solar systems to take hold on one average planet) And if yes, how'd you get back home and tell everyone about it? Or even survive at the first place when all your hi-tech gadgetry would fail you? (thinking of cyborgs and other implants)
So yeah, it'd be too much of a head and continuity ache to force in actual sy-fy nations. That's the main reason why I came up with the high-tech killer radiation. I wanted Medivo to be part of the brikverse as a whole, but at the same time, keep it at it's own micro-continuity.
tl;dr - nope, never gonna happen. Or at least at the moment that's how I feel.
Although I had a discarded storyline lying around here somewhere of a lost DHSM's pod which was on the planet for a while... *will share/tell if anyone's interested*
