Stormcallers
Stormcallers are parasitic cultists who follow the Weeping Dragon, one of four Dreadgods. They seek to advance in the sacred arts through its power.
Ziel’s Dawnwing Sect
The memory of the Weeping Dragon taking up the sky, its living lightning decimating his students and friends, had played in his mind so many times that it had scraped him raw. Dreadgods couldn't be blamed for the destruction they caused; he might as well shout at a hurricane for daring to flood his house. It was the Dreadgod cultists that had stoked his rage, as they looted and pillaged in their master's wake. They had chased down the fleeing Dawnwing sect as rain and thunder poured from the sky. Ziel had stayed behind to hold them off as his junior disciples and students escaped. It hadn't worked. As it turned out, one of the Weeping Dragon's lightning strikes had caused a landslide that wiped them all out. (Uncrowned, ch 14)
