Assuming the various noble factions are jockeying, perhaps a leader emerges, what happens next?
My thinking is that the Emperor sends an envoy of some sort to assess situation and give a recommendation. Noble and other lobbying may of course transfer directly to Altdort (the PC's along to escort their patron would be fun), but the Emperor would want a direct report.
Any suggestions for the sort of official, title, origin of who the Emperor would send for that sort of task. Someone the Emperor trusts, who appears neutral but may of course have their own foibles?
I'm inclined to use (from the Drachenfels novel, which I know is not GW canon) Prince Luitpold, the Emperor's oldest son and apparent heir, who would be just shy of 40 or so. I haven't seen any 3rd edition references to K-F's heir. I would have him arrive with Detlef Sierck the playwright (who would be in his 40's, being born 2476 or so) as a companion, Detlef having heard of a promising actress in Ubersreik.
I have no idea if Prince Luitpold has any "thematic" connection to the mad swan castle prince of bavaria in real history.
