LA Ermor's Dominion Change in 3.15...

[Xavier]

What about a nation of dragons? Ranging from humanoid dragon-kin (I'm thinking AD&D Dragonlance draconions) all the way to full on ancient dragons (which would be SCs at or above the level of Niefel Jarls). In between you have the most powerful of the dragon-kin and the very youngest of the dragons, which can be your stock mages and your non-mage commanders. The whole thing can be summonable (x gems for 5 to 15 of the regular dragon-kin, which are your troops, x gems for 1 dragon-kin mage, and then LOTS of gems, and some research, for the full-on dragons). You can even make it multiple path based, and allow summoning of different kinds of dragons (like the dragon pretenders).

That'd be a non-gold based nation that I think would be pretty interesting, and different from anything out there.
