Divine energy comes from the Higher Powers. When priests pray to their god(s) for spells, it comes to them as divine energy. Like a mage's use of arcane energy to power their spells, priest spells are powered by divine energy.
When a Higher Power is slain, all those that worshiped him or her, lose their source of divine energy. This lasts until they find another god to worship. One of the more recent times that something like this happened was in 1695. In this year, the usurper Raxcvillibus traveled to Coeus's home world and slew him.
