Ed,
Until Perdan and Sirion are destroyed you won't see the light at the end of the tunnel. See, small realms fear realms that are 3 times its size. What do you do? Remain alone and fight until you die or fight with a powerful ally that will give you a chance against that enemy.
I, for one, if were Fallangard I would wanna ally with either Sirion or Perdan so my butt won't get in the first week of life. If you had 20 small realms that wouldn't be a problem, because you are at an equal advantage and disadvantage against them.
Just remember this: People fear Perdan and Sirion and no one wants to fight either alone. It is basically pick a side.
