The Duties of Clerics (EAFW)

Athasian clerics usually possess both a duty and a goal, although these are sometimes one and the same.
A cleric's duty is to live up to the pact he made with his patron. Water clerics, for instance, must always preserve water and try to encourage others to do the same. Fire clerics wish to replenish the mighty forests and cities, but only so that their lords can revel and feed in the flaming destruction. Clerics must encourage the spread of their particular elements and preserve and protect whatever quantity remains.
The goal of the cleric is not bestowed upon him by the mysterious beings that have granted his power. Rather, his goal is that which motivated him to call on the elemental planes in the first place. The vast majority of clerics are con- cerned about the fate of Athas and wish to stop the devas- tating practices of the sorcerer-kings and the reckless defilers. Others have different motives. Some may seek revenge for real or imagined wrongs, others may strive to pro- tect their clans and tribes, and still others simply crave the staggering power offered by desperate elementals.
