Free Encounters!

Here are a number of brief encounters fully compatible with the Knights of the All Mind rules set and easily convertible to other OSR/D20 rules.

"The Planet" or something.
By myself & Postman Bob circa 1993 (except updated monster stats).
Rabbit Holes, a very simple railroad to anywhere in your multiverse...
Here is a Vacuous write-up of the Storm Spirit dudes from that famous movie with Jack Burton. Thanks to "Brown Hood" who posted his original stats back in 2002 on EN World.
