Oh, those dates line up close enough that we could almost be from the same timeline! The Mugunghwa departed in 2395, so that gives them another 120 years for the first successful colonies to get going...

Unless "Earth that Was" means that the planet was wiped out, or something. I'm pretty sure it's still there in my timeline, so that would throw that out. Otherwise, I had been in cryostasis for just under a hundred years by 2518.
