Priest Classes:
There are three types of priests on Athas: clerics, templars, and druids.
The cleric is a free-willed priest, tending the needs of the local people with his particular talents. On Athas, clerics draw their magical energy directly
from one of the four elemental planes: earth, air, fire, or water; not from any manner of deity.
The templar is a regimented priest devoted to a single sorcerer-king. Such disciples work within the hierarchy of that particular sorcerer-king's clergy, advancing in power and position. A templar draws his magical energy through his sorcerer-king.
The druid is a priest tied to a particular feature or aspect of Athas. Unique geographic features are guarded by spirits when druids serve. For example, a pooled oasis has its own spirit and a single druid will reside there to protect it and preside over its use by humans, demihumans, and animals.
