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.
Four Cults
There exists on Cradle a cult for each Dreadgod. Each Dreadgod cult is comprised of parasitic sacred artists who follow their chosen monster and benefit from the destruction it creates. The Path of each different cult use aspects from their specific Dreadgod, borrowing power from it to create Blood Shadows, Living Lightning, etc. etc.
- Redmoon Hall, with their Blood Shadows in a thousand different forms, follow The Bleeding Phoenix
- Abyssal Palace, their faces concealed beneath hoods and stony masks, follow The Wandering Titan
- Silent Servants, whose mouths are bound, follow The Silent King
- Stormcallers, who ring their arms in scripts that crackle with lightning, follow The Weeping Dragon

Ziel’s Dawnwing Sect
In book 4, Skysworn, Eithan says that the dreadgod Weeping Dragon was sighted on the Iceflower Continent only the year before. This is where Ziel once lived and taught his Dawnwing Sect disciples. This potentially narrows down the timeline for when the Stormcallers slaughtered his disciples. (Skysworn, ch 6)
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)
Pact with Reigan Shen
In the epilogue of Underlord, the conniving Reigan Shen recruits the four cults to his cause, to represent him in the upcoming Uncrowned King Tournament. In subsequent books he uses them in various schemes, ultimately to gain the power of Subject One, who is also a Dreadgod — the first one ever, locked inside the Labyrinth. He doesn’t tell them the whole truth.
