From the introduction:
Civilisations have arisen, empires have come and gone but the temples of the Gods remain constant, involving everyone in their rivalries and machinations. Political intrigue is almost a sport amongst the clergy and a talented individual can keep their purse full by serving the many and varied clandestine causes of the twenty-seven priesthoods.
The Eldoria campaign setting is an immersive world of dangerous liaisons, mystery and expeditions down dungeons deep.
