Exactly what it says on the tin! @March-Hare and I make the designs for the characters in our book, and I decide to draw them should I get the chance! This'll basically be random illustrations of additional characters besides the main cast (maybe) and more than one illustration of the main cast.
Exactly what it says on the tin! (Head)canons, miscellaneous stories (that may or may not be real, you decide!), and even stuff like planet descriptions! Have fun!
