|Simplified map of the upper level of B1, cartography by Mike (original drawing) and Arzon (blue map) of Dragonsfoot. The full-sized map can be found linked in this post.|
...thanks to the free pdf from Wizards, take a look at the B1 page on the Zenopus Archives website for trivia and links to resources for use with it, such as the simplified map of the upper level made by Dragonsfoot members (for use if tricky mapping drives you and your players crazy) and the not-to-be-missed B1 sourcebook assembled by paleologos (link on B1 page). I've just made some new revisions & expansions to the B1 page, motivated by the new pdf availability. You can also click on the B1 tag below to see previous posts I've written about B1 trivia & artwork.
