There's just a few things that annoys me a bit.
First of all, is there any maps of the planes floating around out there? There's several realms mentioned on planewalker.com and on the MotP, but I haven't been able to locate maps of these small parts of the infitive layers yet. Does they exist?
Second, there's the gods.
I want them all in the Planescape multiverse of course, and in the Deities and Demigods, they've made up cosmologies for each pantheon.
Where did the Greek, Egyptian and Norse gods reside? Detailed answers, or links, are appreciated (:
(And I just thought I'd mention it. After only playing DnD for some months, my players are really interested in starting an adventure in Sigil (we've based it on core setting so far) I'm going to DM the planes! :D )
The Norse pantheon mostly resides on Ysgard, although I believe Loki has his own realm in the Abyss.
The Egyptians... good question. I know Nephthys is in Pelion (Mithardir) on Arborea, Set is somewhere in Baator, and Anubis is on the Astral as the Guardian of the dead gods, but I don't remember about the rest.
The Planescape setting isn't terribly big on maps, in general, because of the infinite size and mutable nature of the planes. However, the Planes of Chaos, Planes of Conflict, and Planes of Law boxed sets all had beautiful poster maps of the Outer Planes, some more useful than others. Also, "In The Cage: A Guide to Sigil" has a couple maps of the city.
What is "On Hallowed Ground"?
Bonemage; I know perfectly well how the planes work and all that. And I would also belive that the realms remain in the same place, as it would be a waste of the gods powers to move them around, same (while less so) about changing the realm.
Oh, and not to sound like a broken record, but on the planes, maps really aren't that useful. A deity's realm, though finite, is so sodding large that a map really wouldn't be practical. I know what you're saying, but realistically speaking, you should concern yourself with detailing small points of interest within a god's realm, not the realm itself. You could just have your players ask what the "general direction" of a point is, (assuming they can even ENTER a certain power's realm,) and go from there.
The Greek have pretty much been taken care of, save that Arborea is home to the actual Mount Olympus. Hecate has two realms, a primary one in the Gray Waste, and a secondary in Baator. Also, the Furies are supposed to reside somewhere in the Gray Waste, and don't forget about the Titans, which are imprisoned in Carceri.
The Norse have also been taken care of, except that Loki's secondary realm is in Pandemonium, not the Abyss. Also, Hel's realm is in the Gray Waste. Bragi has a realm in Elysium, and the Norns reside in the Outlands.
Now, for the Egyptian. They're spread out everywhere, so I'll try, but my sources might be outdated and wrong, so if anyone wishes to correct me, do so. First, Ra, Isis, Osiris, and Horus all share a realm in Arcadia. Isis has a secondary realm in Elysium, and Nut also has a realm in Elysium. Horus is rumored to have a secondary realm in Mechanus, but since he's chaotic, that might not be true. Set's realm is in fact on Baator. Shu's realm is supposed to be the the Elemental Plane of Air. Nephythys realm, as mentioned above, is on Arborea. Same with Anubis guarding the dead gods in the Astral, except that he is now known as the Guardian of the Dead Gods, or sometimes Chac Mool. Tefnut's realm is located in Bytopia. Geb is supposed to have a realm in the Elemental Plane of Earth. Ptah can be found in the Ethereal Plane. Thoth's Estate is found in the Outlands. And Anhur has a realm in Ysgard.
I need to get my hands on those Planescape products I guess. I've looked at that svgames site, but I'm not sure how it would work, seeing as I'm not american, and I don't have a creditcard, nor a connection to download those pdf's with.
But on the locations, I'm pretty much free to put their realms anywhere on the layers then, without worrying that "that realm should really be between that other realm and that one" and so? Good.
(And for those who might have misunderstood my intention, I didn't mean a detailed map, I just meant something general. Are aforementioned maps featured in the pdf's by the wayt?)
Oh, and I've downloaded that web enchantement on Modron, I wouldn't want my players to miss those ;) Also got everything downloadble from planewalker.com, and I've read quite a lot at mimir.net.
Should be a good campaign (:
I think that, if you're starting a Planescape campaign, I would try to give you some advice. Namely this: always try to impress upon your players the power of belief. This is the force that shapes the multiverse. For specific advice, try to play up the factions in your campaign. If you've seen planewalker's faction chapter, it has what you need to know in order to run factions the new edition. If you want some of the factions from the old edition, traditional Planescape websites abound that can help you, and planewalker does include some feats that work for the old factions. The reason to include factions is that it's an easy way for players to create a character with set beliefs. I know that any time I make a planescape character, I'm never content with the basic philosophy of any faction, so I try to give my character a unique twist on it. Which is always good, since it means that they are more defined than they would be otherwise.
Always remember that though belief runs the multiverse, (the outer planes anyway) belief is best used subtly. For example, in a game I ran for my players, I used a hook in a book I read (I believe it was the planes of conflict boxed set) in which a small sect of druids asked the PCs to investigate rumors of a succubus and red dragon taking up residence in a section of the beastlands. Now, rumors of this evil pair hiding in the place had been going around for over 50 years. Now, because belief fuels the planes, the characters realized that the home of this pair would have eventually shifted into the outlands and then into the abyss-because of the apparent 'chaotic evil' alignment of this dragon and tanar'ri. A being exuding a powerful alignment radically different from the surrounding plane will simply not be tolerated by the plane itself. Because they HADN'T, the players realized something was wrong. The truth was that a celestial (a deva) and a fiend (an erinyes) had fallen in love and were hiding from their respected races and basically fearing for their lives. All they wanted was to be left alone. Because this was not an 'evil' or even 'chaotic' motive, they were alllowed to live in peace by the plane itself. Although this is a huge example, the same can be applied to characters on a smaller scale. Xaositects, who whole heartedly believe that the secret of the multivers lies in chaos, you can hint at odd occurances whilst in the presence of one or more of them. Ex. "You know, ever since that group of chaosmen started staying at the inn, fights have been occuring much more often. And over the silliest things too! What? The chaosmen? No, they don't have any thing to do with starting the fights- they aren't even present most of the time. Wierd, huh?"
