Why not a zone based around packs where many of the enemies are tied together like all different kobolds with a kobold brood mother miniboss and a dragon final boss with many bad ends for them themed around the idea that you become part of the pack maybe a few where you end up as one of the normal enemies roaming about or being laid as an egg by a breeder to hatch latter. if you want to be extra could have them monster you interacting with the other enemies in different activities to really sell your part of the pack.
