The Mines of Strorburim in Review
The PDF lacks bookmarks and is long enough with enough different sections that these would be useful. Navigation is okay. The text maintains a single column format and some minor errors were noticed. Bar the covers and maps, there are no illustrations. Presentation is okay.
This is actually a pretty short adventure. Though there is a wilderness area to explore, it could perhaps be better developed by the GM. The mines themselves are small, with only a few different areas; the occupants of the mines, however, are dangerous, and small does not mean easy. In theory, it should be easy enough to drop the adventure into most fantasy settings. The Mines of Strorburim can be found by clicking here.
