The left panel has three items. The big one is my Carousing Mishaps chart. I don't think I've ever needed it, but the other chart here is my Random Dungeon Motivation chart. (Both these charts can be found in the back of Broodmother Skyfortress, by the way.) The bold text in the bottom left corner is my personal motivational quote:
I am the maze controller, the god of this universe I have created. The absolute authority. Only I know the perilous course which you are about to take. Your fate... is in my hands.
That's a line from Mazes & Monsters, the Citizen Kane of Tom Hanks lost in the steam tunnels movies.
Oh yeah, there's also a skull. Just for my amusement.
This photo turned out terrible. Don't bother to click on it. You'll have to take it on faith the this page is devoted to the Arduin crit chart. Turned sideways and slid in much later is one version of my personal attempt to revive Chainmail-style 2d6 spellcasting. I never used this chart for every spell cast in the game. I kept it handy for when wizards try something foolish and/or outside the scope of the rules.
So now I have to figure out what I what to do with a whole nother panel. And I can probably replace the Random Motivation chart with something else, since I've never used it.
