I'm just calling out the readers of this blog, stock this dungeon.
Rules- pick an old-school or retro-RPG and use that game to stock the dungeon yourself (and share here of course).
Reward- praise and adoration of your fellow readers and myself.
I'll also whip up a pdf version of my favorite(s) to share with everyone.
