If you do border with LA Ermor, and you aren't shaping your strategy around taking them out VERY soon..... well, it's no guarantee that they will win the game (but it makes it more likely), but it IS a guarantee that you'll die to them.
While we do not yet know if we will be sharing a border with Ermor the Giants of Hinnom fear no one. Although the maggot infested undead do kind of make our skin crawl.
