Mourngloom Keep for Shadowdark RPG

Levels 1 to 9

Consumed by the pursuit to distill the pure essence of death itself, Sareth built an underground fortress to surround his necroalchemical laboratory.


Overview


Legends speak of Sareth of Daudenmyr and his discovery of the Ultima Letum: the distilled essence of death, a single drop of which could fell a god. But his secret experiments eventually led to his prosecution. As he awaited trial, Sareth is said to have recorded his vast knowledge of necroalchemy in a small crimson-leather book known as the Red Rubric. In exchange for the Red Rubric, his sentence was commuted from death to banishment. Fleeing to lands where his name was unknown, Sareth built the underground fortress of Mourngloom Keep and continued his pursuit of the Ultima Letum.

Mourngloom Keep is the subterranean fortress of a notorious necroalchemist, dedicated to the pursuit of the Ultima Letum--the very essence of death.

Versatility


For each NPC encounter, the Fantasy Grounds adaptation also includes a list of recommended alternative encounters based on party level. The list ranges from party level one to party level nine, assuming four PCs. Using these lists, the GM can quickly adjust encounter difficulty to match the strength of the party.


What are Dungeon Domains?


Dungeon Domains are hand-drawn geomorphs representing sections of dungeons, caverns, sewers, or catacombs, fleshed out with flavourful and detailed descriptions of each area, as well as a unique legend explaining the dungeon's history. Every Dungeon Domain has been designed to connect seamlessly with any of its sister products, allowing GMs to construct or expand dungeons of any size with minimal effort. The Fantasy Grounds adaptation includes two versions of the player map: one with open map edges allowing for expansion, and one with closed map edges for using this product in isolation.


No A.I.
