I was looking for more Drow to run a quick conversion of D3: Vault of the Drow and this works perfectly. This set includes a good level spread to provide some harder drow to put up against the players. Saves me a lot of work! The production quality is awesome too.

This is a great romp through the Underdark. A really cool thing to read (and run!) in 5E. You could definitely mine this for some cool alterations to Out of the Abyss or any Underdark campaign.

Ran this adventure and did a quick conversion to 5E. It's wonderful. The maps are huge, there are interesting places to explore, and it is filled with ideas. The bundle that it's in is definitely worth getting as well.
