Taking a big step...

So, I've decided to whip up something for that One Page Dungeon Contest everyone is so high on. It will be my first attempt at making a dungeon in almost 15 years. I thought long and hard about what to do, and came up with a seemingly good idea. I already have the map roughed out (plus some room to expand), and some ideas for the dungeon itself. Now, I just need to decide how deadly to make it, and what stock it with.
