Interestingly enough, the only large armies we've seen are those in the Empires of Bodily Fluids. The Azurites certainly don't have tens of thousands of soldiers at their disposal. The Elves presumably don't have a large army available either, or they wouldn't rely on inserting commando teams (a classic tactic for a state that wants to fight a war on the cheap). The various humanoid nations on the Southern and Northern continents are divided amongst themselves, and among the most powerful of them recognize Gobbotopia. Nothing can be said of the Dwarves, but they are far away.
