There isn't one.
System Failure had mention of the coup's effects in the Tir (and you're right, Surehand and most of the other old Princes got booted). Most of the old guard are exiled and some are actively hunted, Larry Zincan (the ork) is the new High Prince, and the Tir's border paranoia and xenophobia has...softened, somewhat. It's a kinder, gentler, less-awesome (IMO) Tir, in summary. There aren't many details, though.
Sadly, none of it's all been spelled out in one book. Uhm,
yet. I'm desperately trying to find the time to actually sit my ass down and write up a
Land of Promise e-book proposal and send it in to the Powers That Be, though...and I like to tell myself it'll only be a matter of time before I'm able to scratch this itch (not only for all the other Tir fans out there, but for myself, a rather rabid one).
In the meantime, take solace in the new, now canon, Portland Paladins Urban Brawl team! Something positive came from their nasty old anti-elven coup, in the end.
