I recently contributed to an awesome project that is Kickstarting now. The Book of Dungeon Encounters is a collection of system-neutral dungeon encounters you can drop into any dungeon setting. If you like creepy, cool, fun, puzzling, or challenging dungeon encounters, don't miss out on this! https://www.kickstarter.com/projects/philipreed/the-book-of-dungeon-encounters-for-use-with-fantasy-rpgs/
