If memory serves Tom will eventually get around to deleting the realm from the database, at which point I expect that one person would end up being a rogue.
Indeed.
And what if get enough volunteers to start a take over on any rogue region?
It would be fun to see!
Maybe... but extremely unlikely. Plus, he's not a hero. He'd need to be in a region of his realm to change class, which is currently impossible. And had it been, priest would have been a better choice, for the use of "claim region".
However... I don't know... It used to be possible to swear fealty to a guy just by being in the same region as him. Not sure if that's still possible. Not sure if anyone really cares to recreate Minas Ithil, either.
