Greetings, people of OA

[Rynn]

With the data you have provided, ~2800 AT as a starting date should work, then. Thank you for informing me of the problem. Also, thank you for linking me to Ran to get an idea of the structure of how to organize a system like this.

We've recently updated the First Federation, an important political union of the early timeline. It began to fall apart from the 17th century AT, and at this point starships capable of up to .35 were available. Perhaps your colonists could leave around this time, and perhaps rather than launching from Sol they could launch from a Federation system that is a bit closer to the destination? E.g. start them off in a system 50ly from Sol in the direction of Rho Ophiuchi, a .33c launch in 1600at would arrive after 400 / .33c = 1200 years, pegging arrival date at 2,800at.

Faster ships tend to be sleeper ships, but you could also have it be a data ship with each individual uploaded. They could either stay in storage for the journey or live in a virch. With the latter option you could have the virch run slow to make the journey seem faster. The S2 could be an S1, or even a modosophont, who is present for the journey.
