Because we already have the goblins, gnomes, humans, elves, penguins, and vampires, trying to take over RS. That's why. hmm.. i actually wonder why haven't the "most powerful beasts" called dragons tried to rule rs.. afterall they would make hell of a army.. :-s because dragons (which are not the "most powerful beasts") are not the quickest of cats when compared to other creatures. you see, without the dragonkin, dragons wouldn't even exist. whereas some monsters, like the tzhaar, have built a city, introduced us to obsidian and onyx stones and jewelery, and control Jad. see what i'm trying to get at? EDIT: also, i doubt an army of dragons would last long against an army of tzhaar with a few Jads among the soldiers
