Dungeon Plane

Long ago, in my 3.5 campaign, the party found itself on the "Dungeon Plane".  All I knew about that plane at the time was; it was "old school" (so only spells and powers/feats from base (DMG, PHB) books worked) and it needed to be randomly generated endless "mega dungeon".  Wanting to avoid distraction of rolling up during game but wanting the dungeon to be unknown even to me I wrote this little DMG Appx A Dungeon Generator program to automate things.

Here's what it looks like running.  It's text mode prompting "Adventure awaits:" which I either respond with to generate another "roll" on charts or respond with various commands that roll on specific sub-tables.

Random Dungeon Delve.
