Dreadgod cult

The Dreadgod cults first appear in action in book 4, Skysworn, when The Bleeding Phoenix awakes and its cultists, Redmoon Hall emissaries, attack citizens in the southern Blackflame Empire. However, we hear mention of the cults before book 4, because Yerin has a blood-shadow belt.

Simple Summary

Cultists are key antagonists throughout the series. Yerin calls them all parasites; she particularly personally has reason to hate Redmoon Hall, followers of the Bleeding Phoenix. Ziel hates The Stormcallers, who murdered his Dawnwing disciples on the Iceflower Continent. He especially wants vengeance on the Stormcaller Sage who splintered his spirit.
In the epilogue of book 6, Underlord, Monarch Reigan Shen recruits the four cults to his supposed cause, to represent him in the upcoming Uncrowned King Tournament. In book 8, Wintersteel, Shen persuades them to ambush the Akura group in Sky’s Edge, and to kill Akura Mercy and her brother Pride. His plan fails when Lindon comes to the rescue, advances to Sage, and attacks several of the high-ranking cultists. In book 10, Reaper, the cultists wage a false war on the mountains around Sacred Valley simply to distract the other Monarchs from what Monarch Shen is up to, down in the Labyrinth. Unbeknownst to the cult leaders, the mighty Lion King has been lyin to every dreadgod dupe, to enact his plan for world domination.

Four Dreadgod Cults

Each known Dreadgod is followed by a cult, sacred artists who follow their chosen beast and benefit from the destruction it creates. The unique Path of each cult uses the same aspects as their Dreadgod, borrowing power from them to create Blood Shadows, Living Lightning, etc. They murder innocent citizens fleeing from the Dreadgod, just to attain greater power.

1. Redmoon Hall, with their Blood Shadows in a thousand different forms. Dreadgod — Bleeding Phoenix
2. Abyssal Palace, their faces concealed beneath hoods and stony masks. Dreadgod — Wandering Titan
3. Silent Servants, whose mouths are bound. Dreadgod —- Silent King
4. Stormcallers, who ring their arms in scripts that crackle with lightning. Dreadgod —- Weeping Dragon

Secret Keeper

Elder Whisper sat on his haunches,
tails waving smoothly behind him.
“Wei Shi Lindon. Would you like to
know how to kill the Dreadgods?”
