Descent Into Darkness


Deep in the north Svalich Woods in the forgotten cemetery of Marescu’s Vale—now known as the Vale of Tears—a ghost has a problem. Islana Marescu is the youngest daughter of Baron Liviaz Marescu. Islana is also a ghost who never died. Brave adventurers liberated her from the curse of a dark necromancer (see The Weeping Revenant for how your players can take part in that story), but now she is captive to the Vale. Descendants of the Marescu family hold the key to her freedom, a family she can no longer trust.

For over two hundred years Islana Marescu has existed as an undead creature, transformed by a curse of darkest evil. Only the Ruby of Rastlova prevents the curse from inflicting its most horrific effect on Islana. Islana longs to be released completely from her undead existence even knowing it will mean her long-awaited death. During the many years she suffered under the full effect of the curse and wandered as a tormented revenant, Islana learned that a clan of Marescu descendants holds the key to her freedom. To secure Islana’s release requires a descent into a place of deepest darkness where fiends of the Nine Hells await, a task only the bravest dare undertake.

Descent Into Darkness is the second title in the Desolation of Marescu™ series. The adventure is designed to function either as a stand-alone adventure in an unexplored corner of your campaign world or as a side adventure within a Curse of Strahd campaign. Designed for four 4th to 6th level characters, it contains difficulty adjustment suggestions for parties of both higher and lower character levels.

This adventure guide contains a complete story arch that combines an array of engaging monster encounters with a custom NPC interaction mechanic that replicates the challenge of gathering reliable information during interactive scenarios in which the player characters must pit their wits and charm against shrewd and deceptive NPCs. In addition, this adventure guide includes several 5th edition conversions:

  • three monsters absent from the Monster Manual and Volo’s Guide to Monsters
    • the Black Abishai, a gargoyle-like devil that is a vicious torturer and serves as a warden of the Nine Hells
    • the Kocrachon, a diabolic inflicter of sick and horrific tortures on damned souls sent to torment
    • the Legion Devil (Merregon), Hell’s weakest foot soldier that when encountered in numbers seem to form a sort of group mind that can easily overwhelm powerful foes
  • two magic items absent from the Dungeon Master’s Guide 
    • the Devil Bane
    • the Great Cli Lyre

What makes this module stand out is it's emphasis on problem solving outside combat (though the combat is also engaging and challenging). I love that social interactions play a key role in the party's success. The story is well written and stylish. I [...]

Rules Edition(s)
Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
