By now, you've probably seen the D&D game I ran for the writers and producers of Robot Chicken. It's all over Youtube (with and without DM commentary). The adventure, which I've since taken to calling "Tomb of the Orc Slayer," unfolds in a dwarven sepulcher nestled amid the greater dungeon complex of Undermountain, below the city of Waterdeep.
I'm giving serious thought to submitting this short adventure for publication in Dungeon magazine, along with adventures for the other two dwarven tombs mentioned in the videocast ("Tomb of the Heartless Dwarf" and "Tomb of the Iron Warlord"). Each tomb would serve as a standalone adventure, or they could be played as a series that concluded with the heroes acquiring three dwarven shields needed to unlock a secret dwarven vault within Undermountain itself. (The vault is something I hadn't considered building an adventure around. Hmm. That would make for a very interesting adventure design contest, wouldn't you think?)
Let me know if this "tripartite tomb" series is something you'd like to see. If there's sufficient interest, I will endeavor to carve time out of my crazy schedule to make it happen.
