Totally changes the content of the post.
The Legion has always had the 1,000 years in the future focus. I mention this an awful lot, but that leads to shifting timelines as the year itself changes with real time. Start the Legion in the year 3247 and stick with that. 1,000 or 1,200+ years when talking about speculative future fiction doesn't matter much. No more sliding timelines and the year is a nod to longtime Legion history.
