The Ruins of Undermountain - The Entry Well and Environments


The Ruins of Undermountain - The Entry Well and Environments are intended as an introduction to the Undermountain dungeon crawl, converted to 5th Edition Dungeons and Dragons, which includes a detail backstory about Undermountain, Halaster Blackcloak and his apprentices. These rooms are drawn from official D&D releases that include the original Ruins of Undermountain Box Set, plus some additional rooms that were detailed years later, while the rest of the rooms were designed for my own campaign. This module ignores the changes done to the dungeon in the 4th Edition release of Undermountain, and is designed to be set Pre-Spellplague (roughly late 1379 DR in Forgotten Realms).

This area represents the locales that are commonly explored by most adventurers who enter the dungeon via the Yawning Portal, thus they have nearly all been explored before by other adventurers, many of which have left their mark on the dungeon crawl over time (but there's still a lot of fun things to encounter!). The DM could provide a crude map of some areas of the area, although I wouldn't make it entirely complete, nor accurate (the later provides a lot of amusement). The DM is encouraged to roll random encounters from an existing encounter table (or use my own custom Undermountain Random Encounter Tables & Rumors is available on Dungeon Masters Guild). I've also produced two follow ups to this module that explores the areas to the west of the Entry Well called The Lanceboard Room and Librarium Environments, as well as the southern areas, The Grim Statue and the Labyrinths EnvironmentsThe Northern Reaches and Environments, and the Western Reaches and Environments. All my PDFs on Undermountain can also be purchased together as a bundle, which includes some additional monsters from Trobriand's Scalandicals. It can also be found with all of my PDFs in EVERYTHING ANDREW JAMES WOODYARD BUNDLE, sold at a considerable discount compared to the combined retail price of all the PDFs contained within it.

The Map provided is taken from the original map of Undermountain, but the room numbers have been altered for the purpose of this module. In addition, I've included descriptions of the Yawning Portal for the DM's use, and to make descending into Undermountain a memorable experience.

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.
