And now for something a little different!
This idea actually came from my friend Luna, who saw this person in a dream! They're a professor at a magic school. You know those magic schools: the campus had a lot of latent magic floating around. So they probably shouldn't have been surprised when they put up a job posting and the tree in the courtyard walked up and applied! Technically, they are the school's oldest alumni: every time a student did their homework under their branches, they were watching!
Nowadays they're the head of their department! They take some getting used to, but they're a fair and patient professor!
(I also really wanted to try drawing with a textured brush! I think I need to tweak some things, but it was fun!)
