Did I make a whole character based on a hairstyle I liked? Yes. This will be a trend don't you worry.
Witch, priestess, fae hunter, voodoo woman, whatever you want to call her it doesn't matter. Tituba "Tia" Jones has grown up alongside the other half of the Veil between worlds. She inherited her practice from generations stubbornly holding on to their heritage. Whereas John knows how to deal with ghosts, Tia deals with everything else. She knows the rules and she knows the weaknesses. If you come to her door after weird feelings and stubborn hallucinations, she might be able to help.
Tia is good hearted but guarded. A part time student far from home, she's only hear to fill in a few gaps. Her and John became friends when they both corrected their professor on how Lake Lanier came to be. When she has ghost trouble, she goes to John. When John has fae trouble he goes to her. Her paranormal experiences are much less wholesome, but much like John, they push her to help those in need.
You'll be spending a lot of time in Tia's house. She's on the fast track to becoming a more social and open person lately, but we'll see how long that lasts when she runs out of solutions for problems.
