[Daring Scylla]

Stereotypes are there for a reason - sometimes they work. besides, i think these witches seem more trope-y than cliched. I think I'd let you choose which witch (lol) to lead me would make it more fun - a mystery for me.
the character I'd want to use would be originated in earth - a pixie boy, so he's of the Fae but he's not powerful or anything. He's rather average which makes him interesting to me.
Different worlds to explore - perhaps they find a fracture in the fabric of their world leading to various parallels? or time travel? or an unsavory combination of both?
perhaps a god/gods have called them or are directing the witches? I don't know. Run with it. I'm turning in for the night but I'll be back on tomorrow with more ideas.
