Yep, these sure are walls of the inside of a pickle. You drew on them with some chalk. The sound wasn't horrible, but it wasn't the desired chalk noise. You ran out of the blue chalk 4 separate times and to use a total of 5 different blues.
Your process started at the center with a miniature version of Skaia at the center of the door, then you drew the frog planet and the moon with all the Prospitians. Then you rendered the other two interior planets, the one of dragons and the other of puppets, then you rendered the last two planets in your session. The one of lava, and the other of your former employer. You then got to drawing the cosmic membrane between the planets, and that's where you ran out of chalk several times.
You like to do this, drawing, whenever you're bored and have nothing to do. You were actually the inspiration for the famous Da Vinci painting where there's a man with 4 arms and 4 legs and his penis hanging out. He was dreaming of Derse, and then saw your little doodle of a man with a doodle, and then he drew his famous drawing. You watched in jealousy at him getting fame for your work. That's part of why you hate Italian people. Because one guy 600 or so years ago.
You've done other doodles, mostly of the things in your life that you hate. It's much like the players and their doodles, they do almost the exact same kind of thing. You've drawn about the queen a whole lot, and some about your job, some about the state of the kingdom, some about women who refuse to go out with you, and other things akin to that.
