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.

The Plane Below: Secrets of the Elemental Chaos (4e)

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

This book also expands on demonic lore. This time for 4e. Though this book also expands on various chaotic and elemental forces. Making the connections between the Abyss and elemental chaos stronger.

This is divided in five chapters.

Chapter 1: Chaos Incarnate

This chapter covers the nature of the Elemental Chaos of the Astral Plane. You can see the start here of why Wizards of the Coast is setting Spelljamer in the Astral and not Wildspace. It makes sense. This deals with the nature of chaos, traveling in it, and features of the plane including hazards and various skill challenges.

For warlocks, there are even three new Patrons. And "new" cults like the Cult of the Elder Elemental Eye. And "new" artifacts like the Crystal of Ebon Flame.

Chapter 2: Races of Chaos

This covers Archons, Djinn, Efreets, Genasi, Giants and Titans, Githzerai, Slaad, and brief entries on others like Dao, Dwarves, and Primoridals. No stats, all background information.

Chapter 3: Elemental Locales

Various important locales in the Elemental Chaos. These include The Brazen Bazaar, Canaughlin Bog, Gloamnull the City of Rain, Irdoc Morda, the Pillars of Creation, The Riverweb, the Glittering Mine (with encounters), and The Body Luminous (with adventure). Save for the last two there is only minor game-related details. So use in any game would work.

Chapter 4: Into the Abyss

Same title as Chapter 5 of Fiendish Codex I: Hordes of the Abyss this covers similar ground. Travel and hazards of the Abyss, the so-called "bottom" of the infinite elemental chaos. We get a listing fo demons from other 4e books and ideas for adventures and skill challenges.

Some demonic locations are given and these are for the most part different than what we have had before.

Chapter 5: Creatures of Chaos

Now, this is the reason I pulled this one out for today. We get new oozes, new archons, and of course new demons. There are mostly elemental creatures here and chaotic ones like Slaad who are largely chaotic evil here. There are some unique creatures as well including Ygorl the Lord of Entropy.

Great material here.

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?
