Fall of the Warlock Kings
The ancient Dragon Realm, ruled by the children of Tiam, goddess of dragons. In ancient times, long before the rise of civilization on Afyon, there was already a great and powerful empire in Rhu’alan, which sent a massive colony to take over the continent across the Dragon Sea. Little is known of Rhu’alan, save that it is (or was) warmer and wetter than Afyon, possessed of much low-lying land, and that dragons were common there. Some centuries ago, fighting began among factions in the Dragon Realm, and the ancient empire there was torn asunder. The final collapse shattered the realm and killed most, or all, of the dragons, so that if anything remains there, it is unknown to the rest of the world. From Rhu’alan came the dragonborn, and the Seven Dragons who led them to Afyon. The kobolds also claim to have come from this realm, even further in the past, but there are many who doubt their claims.
