Heya! Denizens of the Tower!
It's the end of March and tomorrow the day of bad jokes. Here's a large dungeon where an evil cult have their hideout. It's part of a larger complex of chambers and tunnels under a cemetery. Some of the locations were intended to be mausoleums actually.
The cult worships an occult entity from the void they only know as the "Black Star", but the high priests know better. It is a thing called an Atropus. It is believed to be the remains of a stillborn god, then resuscitated with evil necromancy. The cult's endgame goal is to redirect the course of the Atropus orbit so that it collides with the material plane. You know... basic cult stuff.
The illustration comes in the usual formats but due to its size, the scale is 70px per square for the Roll20 file. You'll find lore and fluff in the PDF file.
Have fun and games on your end. Until the next one, Elven Tower.
