Every sea witch needs a shell spoon! They could be a great witch CRAFT. (Haha! See what I did there? n_n *snorts*)
I've noticed that you mentioned Wiccans a lot. My MC is a witch, and I wasn't really aware of other kinds of witches, even though I did thorough research. What other kinds of witches are there? Just fyi, she is a mostly-closet witch, and uses stones as connections to places. She mostly uses runecasting and entomomancy (especially beetles and spiders). What might she choose to align with, if anything?
