[@Zadubadabu]I will write up my app tomorrow.
EDIT: It'll be about Martians.
[@Flagg]I am thinking of making them the real Martians.
AKA the ones who used to attack the British in the 19th century and then were forced to escape their planet because it became uninhabitable.
Lacking FTL methods at the time they literally traveled thousands of years in stasis and perhaps they had awakened in almost the recent times.
They lied in wait and watched the humans already being a great interstellar empire with envy. They now plan to take over this dominion as it should have been.
Does this sound about right to you?
Hopefully this doesn't clash with any plots. How large was the empire to begin with?
