A module for 4th-level D&D characters, entitled Within the Radiant Dome.
This is a three-level dungeon. It's a site-based module. There it is. Plop it anywhere you wish. It'll fit! No quests or plots. Just good old-fashioned D&D adventure...but all the pieces are new! You've never seen anything like this before: Kong, freaky monkeys, void-craft, mutants, telephones (NOT what you think), the Mirrored Hall (a personal favorite of mine), and...the shit elemental!
Compatible with every old school version of the original fantasy role-playing game.
