Necropolis - originally by Gary Gygax & Necromancer Games
Is now being kickstarted.
There is even a pair of VTT offers for it (Unity and generic VTT assets)
It’s a thick hardcover fully of maps and illustrations. They are having various handout cards and maps as well.
The last hardcover was an amazing and difficult high level adventure written for d20. The new Kickstarter builds on the original and is available for both 5E and Swords & Wizardry (think 0e with all the additional books added JUST before 1E was released)
It looks great and is one of Gary’s best later works (or best but opinions of course can vary)
Don’t miss this Set*
