The first mistake is playing in Luria, a realm with as many (when not more) regions than nobles, and yet basically a continent away from anyone else. The day Luria gets in a war will probably be the day one of its neighbors decides to put it out of its misery. And given the culture of Dwi's realms, I don't really foresee that happening.
A better bet would be in one of those realms that neighbors Astrum, like Arnor or Westfold. Or Astrum itself.
Astrum is forming a huge powerbloc, joy of joys. So yeah, the realm that could probably take on all the realms in its vicinity (besides Westfold) at once is allying with the realms in its immediate area.
