[@Dinh AaronMk]By mainland do you mean the continental territories down South and eastwards to my main island?
Removing that entirely would completely change the demographics and turn Yllendthyr into a quite different faction. Lot less diversity and chance to explore unique cultures. 
So even if I have to take other reductions I'd rather have some continental holdings because that's a core element for the nation's roleplaying style.

The problem is despite that it gives them access to too much undue power in the north, since that solid arch of holdings north to south entirely controls the waters of the north and gives far too much influence to a single person over the others. So you're asked to tone it down and work on getting there through IC posting.
