Wherein your humble scribe, drawing on the “All The Dice” random generator concept (tip of the hat to Grim), presents a random table for your nerdly needs. This table is built for Labyrinth Lord + Advanced Edition Companion. You should be able to tweak it to your needs for just about any other old school fantasy RPG, though.
The Mages’ Desert is an area far to the west of most civilized lands, burned barren by a great magical duel that happened in aeons past. The sheer power of the arcane residue that haunts this place brings very strange storms to the region. The tables below will help construct just such a storm to bedevil your players if they should happen to be passing through. Sometimes these storms are strong enough that they even make their way to settled areas.
