Just a quick note that the long awaited first errata document for Dungeons & Dragons 5th edition has been released by WotC. You can read more about it and download it here.
During the D&D Next playtest, I wrote an original adventure module called The Cavern of Sundark. If you’re interested in playing it, you can download it for free.
I recently decided to update it to be more in line with the final rules now that 5th edition has been out for awhile. The Cavern of Sundark is designed for four 1st – 3rd level characters using 5E rules, although it should be easy to adapt it to other systems. I’ve run two groups through this adventure (several co-workers in one group, and my kids in another group), and everyone that has played it really enjoyed it.
