Why Play Northern Alliance
Because you want to play what is effectively an entire army of good guy vikings, Ice Elf Waifus, Ice Naiads, Snow Trolls (Yes you can field Snow Trolls, they even have their own Hero Unit), Ice elementals, etc. If that's your thing, these guys are for you. There is also a Hero unit named the Ice Queen, and since [Kings of War] is a models agnostic game, you have the perfect excuse to have Elsa lead an army of Vikings Ice Elves, Half-elves, and Ice Naiads (Brigade games has a nice Frostgrave miniature that can be used for such a purpose.
