Lords of the Kings series
A series that tells the tale of a dying realm, Aerdon, and its five kingdoms that are struggling to survive, as the realm inches towards extinction. The only way for the kings of Aerdon to save their people, is to unite and proclaim a single king, something that no one wants. And in order to do that, the kings must venture into the Endless Forest, and find a passage to the other side, where a new realm awaits!
But little do they know, that the real power resides with the Wizard-Gods, the creators and destroyers, the Lords of the Kings.
