The spooky fish witch. Wendy used to be a pretty successful stage actress and singer, but she slowly dropped all that after moving to Hollow Street and becoming decently interested in witchcraft.
Her interest kind of came out of nowhere too, much to the dismay of her brother. She focused mainly on astral projection and summoning though, enjoying having nice conversations with other beings in the Nythe.

But the Nythe isn't always friendly. Everyone knew that, and everyone warned Wendy. Yet she oddly never listened. Not to say she was dumb, not at all. But... that was so unlike her.

She projected too far one day, into places she wasn't welcome. Places she couldn't comprehend.
And after that, the cheerful, plucky, passionate girl that loved musicals and arcades and fashion was gone.

Now she lives as a sleepy meatpuppet, unable to feel any emotion other than mild contentment. She still summons and communes with the outer things though, letting any spirit that needs a vessel use her how ever they please.
