The only problem is, in the FRCS, they lightly encourage you to not necessarily end your old campaign, and continue playing on from 1385 DR and work your way up to 1479 DR. But without more information, other than a very general overview, and absolutely no timeline of major events in those intervening 94 years, it's kind of hard to do this and avoid conflicts with future material covering this period.
Okay, that's a fair point. I didn't realize they were encouraging people to play through that period; I was thinking entirely in terms of campaigns that begin in the new age.
