Demons, as D&D describes them, are Chaotic and Evil. But more than that they are of unrepentant evil. You never hear of demons becoming good, ever. So rare that when it does happen, it becomes a thing of legend. It also means that the only appropriate way to deal with a demon is to send it screaming back to the Abyss from where it came.

So if 2nd Ed AD&D was the golden age of Settings. Then 3rd and 4th Ed D&D was the golden age of fluff and story. Here I have some books about Demons and the Abyss with details that are still in use in 5th Edition today.

Fiendish Codex I: Hordes of the Abyss (D&D 3.5)

PDF and hardcover. 162 pages. Color covers and interior art.

Published in 2006 this product had three aims. First, update all the various demons to the 3.5 D&D rules. Second, introduce new rules about the Abyss and new demons. Finally to provide a more "PG" sort of book rather than the "R" rated Book of Vile Darkness. This book expands on everything we know so far. Indeed for a chaotic race, the power structure of the Abyss has been in place since the introduction of Eldritch Wizardry 30 years prior.

This book gives us the notion, likely introduced in the 2nd E and I may have missed it, that demons are spawned from the Abyss itself, which may also be alive.

Chapter 1: Demonic Lore

This covers what is currently known about demons and the Abyss. It also introduces a new source of demonic knowledge, the Black Scrolls of Ahm. We get a bit on demonic physiology, in this case, a dretch, though it is also noted this can vary from demon to demon. A bit on the nature of death in demons. Demonic roles and possession.

Chapter 2: Demons

Ah. Now I was one of the first ones to complain about the bowdlerization of Demons into Tanar'ri during the AD&D 2nd days. D&D 3rd Edition kept them, but also kept demons. Here is the payoff for them doing that. Tanar'ri are but one of three (in this book) types of demons. Green Ronin began this with their demon books early one and I even did it back at the end of my 2nd Ed days. It is a natural and logical assumption in my mind. And one I am glad to see here. The two new types are Loumara subtype (a new type of demon) and the Obyrith (an ancient, primeval type of demon). Each has different traits. So now demons are listed as something like "Always CE Medium outsider (chaotic, evil, extraplanar, tanar'ri)" or similar. There are still chaotic evil monsters in the abyss that are not any of the three demon sub-types.

Among the Loumara we have: Dybbuk, Ekolid, and Guecubu. For the Obyriths we have the Sibriex. There are more Obyrith lords coming up.

Chapter 3: Demon Lords

Here we have names going all the way back to the beginning, but all updated. The art for Demogorgon reminds me of the cover of Eldritch Wizardry. There are plenty of old favorites here. As well as plenty of new and somewhat revised ones. There are Obyrith lords like Dagon, Obox-ob, Pale Night, and Pazuzu. Dagon has had an interesting history in D&D due to the god, devil, and Lovecraftian creature that all share the same name. This Dagon tries to, and largely succeeds in, uniting all three into one horrible creature.

Chapter 4: Trafficking with Demons

Deals with demonic followers, both human and demon. It's 3.x so there are feats to be had here! There are also new spells and uses for skills. We are introduced to the Black Cult of Ahm and their lore including the various scrolls of Ahm. There is the Abyssal Mundus, the Black Writings, and the Rubric of Tulket nor Ahm. There is also the Transcriptions of Ergon, rumored to be an apprentice to Tulket nor Ahm.

Chapter 5: Into the Abyss

I mentioned this was a golden age of story and fluff, this chapter is a good example. We get a brief history of the Abyss, the various demon types, and of course The Blood War. We also get details on various Abyssal layers and areas. We get Graz'zt capital of Zeltar which exists on three layers simultaneously. The infamous Demonweb, Orcus' layer of Thanatos, and many more.

Appendix I covers all the lords of the Abyss, their titles, areas of concern, and their layers. Appendix II covers the known named layers of the Abyss and their rulers. Appendix III covers demonic monsters from other 3.x books.

Even if you are not playing 3.x or any system similar to it, this is still a great book on demons.

Having the PDFs I am tempted to print out the fluff sections and add them to a guide of demons I have had since the 2nd Edition days.

Maybe D&D is about demons after all?

Don't buy this unless you're a cis het man. 1) it uses "he" instead of "they" when referring to DMs, players, monsters and NPCs, 2) pictures of female characters are highly sexualised, e.g. are naked, nearly naked or depicted with their clothes flying off in one case, and all have the same or similar body type, 3) nearly all female demons are variations of succubi and are described only as beautiful, slender, sexy, shapely or similar, with little attention to any personality traits, 4) it contains the following passages: "most of Graz'zt's priests, known as the Chosen, are female - as testament to his insatiable libido", 5) almost all of the named characters are male. The listing in the appendices has male demons as the default, with a small marker in brackets showing the rare exceptions.
