The Rashidaran is the alliance of Titans, other primordials, elementals, and various others. They seek to unmake all life in the material plane and start fresh. They are opposed by forces aligned with life in general, as well as all of the gods, who would lose much of their power without their believers. This has lead to some bizaare cooperation across alignments amongst deities and their followers. Many druidic orders are split between allying with life in it’s current form, and with the more primal forces of the Rashidaran.
This alliance is aided by the Demodans, perverted creations that some Titans, driven mad by exile from the material plane, created in an attempt to imitate mortal life.
The Titan’s awakening may have something to do with the stirring of That Which Sleeps Beneath.
