I've been meaning to post this a lot earlier. Here's Chelsea who I adopted from  iDoodle2Draw, another really great design I should utilize more. The background for this ref is something I added for it.

I think of Chelsea as a potion and medicine vendor of some kind. Despite her appearance she's always strictly honest about her wares, but she knows she's already instinctively not trusted so she leans into that distrust. Expect cryptic warnings and technically correct information from her.
