This, of course, is the genius of a three realm island - there can't be any stable alliances.
"Sandalak has always been allied with Ikalak and at war with Taselak", etc.
It has more to do with the fact they are all at war because once you kill a realm, you already have your enemy lined up. I have always enjoyed games like that because of their enjoyable diplomacy because its tricky, although much simpler on this island with only 3 realms whereas I have played games where there are 8 different sides.
