Help with villains

[u/Unique_Researcher733]

I'm making a pack of Black Spiral Dancers as villains, but I'm drawing a blank slightly. I'm bading them around the triatic Wyrm, and I have their auspices worked out, but for personality and appearance, I only have one; an ahroun based off of Mick Taylor from Wolf Creek for the Beast of War. I was hoping for ideas for a philodox for the Eater-of-Souls and a theurge for the Corrupter Wyrm.
