Short story, Thulsoma was destroyed, so they moved to Averoth. Averoth was destroyed, so they moved on to Caerwyn. Now Caerwyn is going down, so they're moving on once again. They're not welcome anywhere in the north thanks to the Thulsoma affair. Hence the whole counter clockwise rotation thing, until they've basically gotten themselves banned from everywhere.
