Smog on the Water


The village's blacksmith was accused of producing toxic fumes that killed many people.
However, a persistent tavern owner was convinced it wasn't the blacksmith, but a group of fiendish creatures instead.
The adventurers are here to straighten things up!

A 5-hour investigation adventure for 8th Level characters

In order to raise an army that is not bound to the Nine Hells, Asmodeus commissioned a
sisterhood of night hags to create the yugoloths. The hags crafted four magic tomes called
The Books of Keeping that record all the yugoloths’ true names. Summoning them by calling
their true names inscribed in the Book of Keeping forces them to obediently serve the
summoner. The yugoloths despised being called in this way. Since they have ‘mercenary’
tendencies, they will find any opportunities to misinterpret instructions given to them. They
break promises to find new offers that they favor more. Due to a perpetual quarrel, the
night hag sisterhood fell out, losing the possession of the four books, hence, losing the
control of the yugoloths. Their existences are now heard moving from plane to plane. The
yugoloths can be found anywhere, but their price is usually too high for someone in
Material Plane to pay.

Put an end to the restoration of The Book of Keeping.
Take control or completely obliterate it.

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.
