Burning Chariot & Brimstone horrors:
Exalted Flamer and Furies/Flamers:
I made the Fury/Flamers out of AoS Spirit Hosts. I can either use them as the minimum Fury Auxiliary for an Incursion detachment, or as Flamers of Tzeentch to be summoned when needed. I decided they didn't need to be shooting flames since I painted them as made entirely out of greenish-blue flame.
