I'd prefer some continuity, in Anuire. In part cause of the massive amount of work involved in fleshing out domains and creating some backstory. Might be best to skip a generation though, with the start date being 20 years after, and the tall tales of RoE2 slowly becoming bards tales. Would alow for a lot of the background stuff to be reused, without tying into the current characters and agendas. Woudl also make for some plausible remodelling of domains where they did not fit it, or even allow for some sort of great upheaval if required.
