A Guide to the Ethereal Plane (2e)

Selected Option:
Within the Ethereal Plane, demiplane islands and creatures both odd and dangerous float in an endless field of possibility. Canny folks know that the Ethereal also leads the way to the Inner Planes, infinite arenas of elemental fury. See, it's more than just a backdrop to other adventures - the plane itself offers wonder and opportunity for those with courage enough to explore its limitless expanse.
This guide includes the following information:
  • Ethereal environments and conditions - including methods of getting there in the first place
  • How the alien medium of the Waveless Sea affects combat and magic
  • New spells, magical items, and proficiencies dealing specifically with the Ethereal Plane
  • The chant on demiplanes - islands in the Deep Ethereal that obey no rules but their own - including information on old and new demiplanes, plus DM guidelines for creating these unique "pocket dimensions"
  • A complete listing of the creatures of the Ethereal, including several new monsters and an Ethereal Encounter Table
  • Two new Ethereal-based player character races: nathri and renegade nethlings
Product History

I'm not crazy about the front cover.
There, I've now said the only negative thing I can come up with for Bruce Cordell's A Guide to the Ethereal Plane (1998), one of the later Planescape books and a fine reference to the vast, misty sea of possibility that is the Ethereal.
The Ethereal has always gotten slightly short shrift in adventures, usually used briefly and only as a medium for transportation; all the fun stuff seems to happen in the Astral, such as githyanki, dead gods, and the pathways to the outer planes. This book does a fine job of changing that perspective. Quite cleverly, Cordell focuses primarily on demiplanes, alternate realities, and specific locations in the Ether. This allows him free rein to create unique and spectacular locations for adventure without having to concentrate on what might make an endless plane into a hotbed of excitement.
The portion of the book not focused on adventuring locations covers planar geography; unusual features of the Ethereal, such as Ether Cyclones and Walls of Color; Ethereal magic; and Ethereal inhabitants. As is standard for Planescape, in-character quotes from random adventurers and NPCs pepper the book to provide additional context. The result is a fun, comprehensive supplement that gives a thorough grounding in the Ethereal and still leaves the reader wanting more.
Overall? A Guide to the Ethereal Plane translates beautifully between editions and remains a fun, comprehensive guide to a non-traditional adventuring environment. Highly recommended.
And now, having re-read it, I'm off to go hack together an Ethereal adventure for our D&D Next playtest PCs.

A Grounding in the Basics. Although A Guide to the Ethereal Plane is a Planescape book, it's not intrinsically tied to the cosmology as many other Planescape products are. Of course the book explains how the Ethereal Plane fits into that scheme, but it's much more about the practicalities of Ethereal gaming: Ethereal senses, combat, and the differences between the border and deep Ethereal are all explained in a method that allows for easy insertion of plot hooks. Ethereal combat, for instance, is explained with examples of 3D combat that starts a DM thinking about new and entertaining ways to ambush the PCs. 
Demiplanes, Dreams, and You. When you're sailing a misty and unsubstantial sea, islands of color and matter tend to catch your eye. These demiplanes, small ethereal pockets of unique existence, are the best adventuring locations in the plane. Fourteen of these are presented in the book, along with methods for randomly determining more.
Details are provided for the Black Abyss (a spiraling black hole of entropy and decay), The Boundless (a heavenly refuge that consumes its visitors), Ravenloft, the demiplane of Electromagnetism (about as exciting as you might expect), the demiplane of Imprisonment (a place of great interest if you happen to be Lovecraft fan), the demiplane of Moil (Orcus's sleeping city), the demiplane of Nightmares, the much beloved demiplane of Shadow, the demiplane that Lives (a continent-sized sentient living land that treasures knowledge), the demiplane of Time, the Mazes (an endless trap used by the ruler of Sigil), the Semblance (a wizards' refuge), Wormscape (a solid, three-dimensional mass of writhing worms), and more. The landscape of Dreams is also described, with rules for adventuring inside of dreams. Known divine residences are listed, as are a few structures a traveler may bump into by mistake.
More developed is the chapter with specific encounters, giving detailed encounter locations throughout the plane. Ever wanted to explore the Castle at the Edge of Time, or the web of a massive phase spider lurking in the deep Ethereal? You'll get details of what they're like.

Creatures of the Mist. The monster section is divided between (i) creatures that can see into both the Prime and the Ethereal plane and (ii) creatures that live in the Ethereal (a mixture of brand new and well-known older creatures.) Some old 1st edition AD&D favorites appear here, such as the will, thought eaters (everyone's favorite psionic platypus!), tweens, the shedu, and many more. Your players won't lack for monsters trying to eat them.
About the Creators. ENnie Award-winning designer Bruce R. Cordell has been Wizards' go-to designer for psionics and tentacular monstrosities ever since he authored The Gates of Firestorm Peak (1996) and the "Illithiad" triad of adventures (1998). His most recent novel in the Spinner of Lies series is Sword of the Gods.

I wonder why do you have switched from Applecline to Kevin Pulp in product description. A lot of personal, uninteresting thought instead of a mine of informations... The difference in quality is crystal clear. We had a product story written with a critical eye instead of a screaming advertisement.

Excellent POD. The print quality is good, text is clear, and the cover looks nice, including the original art for the spine of the book. It seems to me like their POD quality has increased recently and it shows in this product.

I have contacted both DMs Guild and WotC about quality problems with this product and they simply don't care.

A Guide to the Ethereal Plane (2e): The cover is damaged (cracks and creases on left-hand side), image is washed out making text hard to read

For those interested in improving the readability and get rid of the "lightness", here is what I did that made it way better.

Used Adobe Acrobat Pro to remove background (low), deskew (low), descreen (low) and sharpen text (low).

I then used Preview on Mac to use a quartz filter to "Lightness Decrease" twice.

You could probably do the lightness decrease just once, I just personally preferred the extra contrast. The background removal was what really helped.

Judging by the preview the scan looks bad. Anyone have this PDF and can confirm?

It's definitely readable, but it's oversaturated so everything is super bright. The Inner Planes has the same problem, but is about 50% brighter so it's a lot harder to read that one than this one.

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.
