Sometimes, a GM wants a pre-made adventure so they can fill in a gap in their own plot. Sometimes, the pre-made adventure is the plot. Rise of the Drow takes players from Level 1 all the way to Level 20, and there's a Collector's Edition that's up on Kickstarter now. Who needs to see the sunshine, anyway?
From the campaign:
This project combines our best-selling, 5-star, ENnie-nominated Rise of the Drow book series into a massive 600+ page, collector's edition hardcover.
Rise of the Drow is a mega-adventure over 600-pages in length and takes your characters from levels 1-20. In addition to the main adventure, you can use Rise of the Drow to run multiple campaigns set entirely underground!
The campaign is over its funding goal, so it's on to stretch goals for the next 28 days.
