The Blazondeer, plus a chart I was working on that was supposed to show all the mystery beings. About 2/3 of the way through I decided I needed to expand the neutral column in the middle into two columns (and re-evaluate everything in it) and add another one at the right though, so I had to abandon it.
As you might or might not already know, I’m currently on a quest to get all 27 (which means 29 since I already made two extras) mystery beings designed. It’s an arduous quest, yes, but I’m not going to stop until it’s done.
Also, if you haven’t figured it out by now (and I’d be really surprised if you hadn’t) each of the mystery beings is slightly themed around a particular attribute(s). I’m in the process of making a rough table of all 29 of them, which consists of three columns: Directed mystery beings, Undirected mystery beings, and neutral mystery beings (can be either Directed or Undirected).
