The Akerou Empire

Deep in the Dragonspeak Mountains there is a reclusive civilization known as the Akerou. The limited interaction the outside world has had with them has been through secretive representatives known as Sentinels. These people handle all interactions, from trade to diplomacy, to the hunting and capture of escaped fugitives from their society that have managed to make it to the outside world. They ride powerful wyverns, a rarity elsewhere in the world, and there are rumors and myths of true dragons living among those icy peaks.
