From publisher blurb:
This product is both a PDF and very large, high resolution map files.
The PDF contains a short history of the region and dungeon, original artwork by Bojan Sucevic, and several random tables for making this dungeoncrawl easier to run and more interesting. For instance, there's a d100 table describing things found when searching a room. There's also a multi-table system for generating fortunes.
Lastly, there's a custom, old school fantasy character sheet created by James V West.
As for the maps, there's an old school blue and white layout of the dungeon... just like we remember from the modules in the late 70's and early 80's. Alternatively, there's a parchment colored map. Each one can be taken to a printer and blown up to 34" x 44". Yeah, that's big. It'll also look impressive on your gaming table!
