The Planes of Law are home to the baatezu, one of the most powerful and terrifying of all monster races!

This new campaign expansion provides all the information necessary for player characters to experience five never-before-explored planes. More than 200 pages detail the lawful-aligned planes of Mount Celestia, Baator, Acheron, Mechanus, and Arcadia, showing the Dungeon Master how to work them into his or her campaign and how to create adventures for players. Deluxe full-color maps and a MONSTROUS COMPENDIUM booklet complete this boxed set.

Product History

Planes of Law (1995), by Wolfgang Baur and Colin McComb, is the second of a trilogy of supplements describing the outer planes of the Planescape Campaign Setting. It was published in February 1995.

Continuing the Planescape Series. By 1995, Planescape's core publishing categories had been revealed, including adventures, a Monstrous Compendium, and a single setting expansion. Now, as Planescape entered its second year, TSR was focusing once more on setting. The previous year's Planes of Chaos (1994) was followed by Planes of Law (1995) in February, then Planes of Conflict (1995) in December; together, they would extensively detail all of Planescape's outer planes.

Though it was a continuation of the series, Planes of Law was organized quite differently from its predecessor. Planes of Chaos had been arranged by content type, including a player's book, a GM's book, an adventure book, and a monster book. Planes of Law was instead organized around its planes. Following a single player's book and a monster book, each of the five planes of law then got its own book — which included an overview, notes on the plane's inhabitants, a geographical tour, and some short adventures. There's a full set of poster-sized maps too.

Based on reviews at the time, the new format was quite successful.

Expanding Planescape. Planes of Law notably expands another five outer planes that had been with D&D since Gary Gygax first laid out his vision of the planes in The Dragon #8 (July 1977).

Acheron, named after the river of woe from Greek mythology, was one of the least-loved outer planes prior to the publication of Planescape. It'd received a one-page description in Manual of the Planes (1987), and that was it. Even Planes of Law calls it "one of the hinterlands". Planes of Law gives more details on all four layers (Avalas, Thuldanin, Tintibulus, and Ocanthus)of Archeron including numerous sites, towns, and realms. It's primarily depicted as a land of warfare.

Arcadia is another name that originated in Greek mythology; it's best known thanks to Virgil and the later paintings of Nicolas Poussin, who imagined it as a pastoral utopia. Like Acheron, Arcadia was never a particularly interesting place for adventuring —a general problem for the Lawful Good planes like Arcadia, Bytopia, and Mount Celestia. Nonetheless, Planes of Law details both of Arcadia's layers (Abellio and Buxenus) and gives particular attention to the dwarven deities, including Clangeddin Silverbeard — one of Roger Moore's creations from Dragon #58 (February 1982).

Baator is the land that had been called the Nine Hells prior to the release of AD&D 2e (1989), based of course on the Hells from Dante's Divine Comedy (1300s). Although the Abyss was the home to the first great outer planes adventures, the Nine Hells received the first great setting articles. That started with Alexander Van Thorn's unofficial "The Politics of Hell" in The Dragon #28 (August 1979). However it was Ed Greenwood who really broke the hellgates with his massive tour of "The Nine Hells" which appeared in Dragon #76 (August 1983) and Dragon #77 (September 1983), and which he then returned to in Dragon #91 (November 1984). Greenwood's first two articles are considered among the best of Dragon's first decade, because they didn't just detail the Nine Hells, but also more generally revealed how an outer plane could be a source of adventure. When Jeff Grubb wrote Manual of the Planes (1987) he referenced Greenwood's writing, which means that the description of Baator found in Planes of Law continues to derive from Greenwood's foundational articles. The first Hellish adventure, "To Hell and Back", appeared a short time later in OP1: "Tales of the Outer Planes" (1988).

As you'd expect, Planes of Law touches upon all nine layers while giving attention to both devils (baatezu) and their lords. The question of whether Takhisis (of Dragonlance) and Tiamat are the same god is also addressed for one of the first times.

Mechanus had been called Nirvana when Gary Gygax first imagined it as a "plane of ultimate Law". It was still going by that name in Jeff Grubb's Manual of the Planes (1987), but he described a void filled with "huge interlocking wheels, like the internal cogs of an ornately carved clock". This led to Nirvana's reimagination as Mechanus with the release of the Planescape Campaign Setting (1994). The source of this change was the modrons, who had been invented in Monster Manual II (1983) by Francois Marcela-Froideval and Jeff Grubb. These orderly, organized creatures then created the basis for an orderly, clockwork world. Planes of Law continues to expand the idea of a clockwork nirvana, though it details just a few of its "infinite gears".

Mount Celestia was originally called the Seven Heavens, but was yet another victim of the bowdlerization of D&D's cosmology in the second edition (1989). The plane was based on the Nine Heavens found in Dante's Divine Comedy (1300s). As with so many of the lawful planes, the Seven Heavens got little attention in its early days, other than the adventure "An Element of Chaos" in OP1: Tales of the Outer Planes (1988). All seven heavens get detailed in Planes of Law. There are also some details on the archons, the race of celestials who exclusively dwell on Mount Celestia.

Future History. Unsurprisingly the most interesting Lawful realms — Baator and Mechanus — got the most attention later in Planescape's lifetime. Baator was visited in the adventure "Fires of Dis" (1995), while two later references touched upon it: Hellbound: The Blood War (1996) and Faces of Evil: The Fiends (1997). Even after the Planescape line wound down "A Paladin in Hell" (1998) and "Guide to Hell" (1999) returned to the Realm. Meanwhile, the modrons of Mechanus got a lot of attention in The Great Modron March (1997), one of Planescape's most memorable adventures.

About the Creators. Baur had previously been the coauthor of Planes of Chaos (1994), while McComb had authored Well of Worlds (1994), so both authors were experienced in Planescape lore when they came together to write Planes of Law.

Why isn't there a printed version?

There briefly was, and I have it -- the thing is, it came just the way you see it in the thumbnail above, with the cover being one of the booklet covers and not the boxed set lid at all.

It was very peculiar.

I wonder if that's why they pulled the POD option? Although the thumbnail/preview had switched from the actual "cover" to that booklet cover image months before the POD went up briefly.

Thanks for the response. Hopefully they will make it available again with all the kinks ironed out. I lost all my Planescape box sets during a move and would love to replace them without going broke doing so.

Same as the comments below. Why is there no POD option for this one? I already ordered Planes of Conflict and Planes of Chaos, and a bunch of other Planescape titles, to go with the originals I have in my collection from back in the day.

I have sent a message to request POD for this title. Previously the 1e Monster Manual ( had an issue where POD was accidentally turned off, which was fixed, so I am hoping the same thing has happened here. I will update once I get a response.

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.
