Since I bought the Manual of the Planes last week and it has one of these for demi-planes, I decided to create a tables for randomly rolling a new plane.

Raven's automated version is here: http://orteil.dashnet.org/randomgen/?gen=PanTED3h
My planeswalker generator is here: http://orteil.dashnet.org/randomgen/?gen=8mw0sYac


======================================
This is designed for 20-sided dice but hopefully I'll find the time this month to convert it and my Random Planeswalking Tables to the online script generator.


Size


Shape


Landscape


Feel


Government and Diversity of Cultures


Major "Humanoid" Races (sort of combines Characteristic and Mid-Range, because this isn't about card sets)


Iconic Creatures



Weirdness

Let's see

I've edited the Races and Iconics slightly.

Burning Earth, your plane is...

The size of a supercontinents or a few continents.
Flat and mostly urbanized.
War-torn, or in the throes of a global revolution.
Has numerous states, cities, empires, tribes, etc.
Is moderately diverse. Besides the minor races, the major races are:
Rhox, Aven
... (you didn't roll enough to finish)


Here's my first totally random plane:

Earth-sized.
A helix, Moëbius strip, torus/wheel, or on the back of a cosmic turtle.
Has highly varied landscapes, and an average feel.
Much of the world ruled by a coalition of factions.
Major races: Fox, Hound or Wolf folk; Amphin; Ratfolk; Snakefolk; Ouphes
Plus a few other less common races.
Iconics: Lammasu, Sphinxes, Demons, Dragons, Hydras
Has highly technological societies of artificers and artifact creatures.

Here's a second plane:

Size of a supercontinent or a few continents.
Globs of land or other solid floating in the air, or on a world ocean, or in a void or a soup of elements. Also bizarre landscape with floating, sideways, pillar-shaped, or inverted land masses.
Highly varied landscapes.
Mostly peaceful.
Numerous states, cities, empires, tribes, etc.
As diverse as Dominaria or Ravnica.
In addition to various minor races, the major races are:
Aven, Kithkin
Dwarves
Faeries, Turtle folk, Vedalken
Catfolk, Surrakar
Snake folk
Satyrs
Humans
Plant or Fungus people
Iconics: Senmurvs, Elementals, Shadow Things, Elementals, Wurms

This is awesome. I'd love to see the randomgen script for this. It looks very promising.

Incidentally, it's possible to call OTHER generators with randomgen--you just have to provide the url basically. So this could be a separate generator and we could still call it in the main generator.

Oops I was just about to post my plane and more dice, then couldn't. Sorry bout the random dice tags

Supercontinent
Flat and mostly urbanized.
War-torn, or in the throes of a global revolution.
Has numerous states, cities, empires, tribes, etc.
Is moderately diverse. Besides the minor races, the major races are:
Rhox, Aven, Homarids (ew), Humans,Orcs, Satyrs, Leonin, Snake Folk, Ouphes

Iconics
Archons, elementals

Wow still not enough. I'll finish it this afternoon

Okay, so I have no idea if this would be useful to you, but using the engine of the random plot generator, I have put together a simple plane name generator. All it does is combine (mostly) two-letter combinations into single-word plane names. Many of them are ridiculous. Others work. Here is the generator: http://orteil.dashnet.org/randomgen/?gen=PanTED3h

And here are some of the more plausible names I've seen come up:

Not sure what you did, Raven, to get "unsafe" backwards.

Emraef!

Thanks guys!

I'm working on one that incorporates all of your table, Arcades. I'm still working the bugs out, and I haven't put creatures in yet, but here's an example (with a silly name...)

Ha! Hairpo...


I may have to rename my plane of Thorneau...


The Night of the Triffids?


I like it.

Flat Ravnica.

This plane name sounds dirty...


Sounds pleasant.


Things don't sound normal at all on Riaten...


"I say!"


I'll be honest, I have NO idea how to pronounce this plane...

Supercontinent
Flat, mostly urbanized
War torn/global revolution
Has numerous states, cities, empires, tribes, etc.
Is moderately diverse. Besides the minor races, the major races are:
Rhox, Aven, Homarids (ew), Humans,Orcs, Satyrs, Leonin, Snake Folk, Ouphes

Iconics
Archons
Elementals
Demons
Phoenixes
Beasts/Dinosaurs

Unique magical effect on every planeswalker who visits

I have updated my original link to the name creator to include most of Arcades's tables. I haven't put in the race tables yet, though, and it might be a while before I can. Still, enjoy!

Nice work, Arcades and Raven!

I just need to mention again that I love this so much.

Rather then roll randomly, I'll take one of my planes (at two points in its timeline) and see where they fit.

Arcnia/The Fractured Lands (TFL)

Size: Bigger than Earth (MUCH bigger. Its a whole solar system. Both)[/spoiler]

Shape: A planet./Globs of land or other solid floating in the air, or on a world ocean, or in a void or a soup of elements./Several polyhedrons or spheres floating in a larger space, with easy ways for mortals to travel between them. Or multiple linked planes. (Seven planets orbiting the host star. Arcnia); Globs of land or other solid floating in the air, or on a world ocean, or in a void or a soup of elements. (Asteroid belt around host star. TFL)

Landscape: Highly varied (Each planet(oid) rolls separately. Both)

Feel: Average. (Arcnia); Idyllic or utopian. (TFL)

Government and Diversity of Cultures: Much of the world dominated by a few factions. (Each planet has its own. Arcnia); One world government, diverse cultures. (Arcnian Imperial Republic. TFL)

Major "Humanoid" Races: Diversity of Races (21+ Anthropomorphic version of every animal vegetable and mineral imaginable; Arcnia. Mostly several unique races, most of which are duel typed (Exmple: Dragon Plant, Bear Hound, Beast Cleric); TFL. No humans or other standard races; both.), Main White Race (Dragon-folk, Illusion-folk; Arcnia. Varies by location, TFL.), Main Blue Race (Dragon-folk, Illusion-folk; Arcnia. Varies by location, TFL.), Main Black Race (Dragon-folk, Illusion-folk; Arcnia. Varies by location, TFL.), Main Red Race (Dragon-folk, Illusion-folk; Arcnia. Varies by location, TFL.), Main Green Race (Dragon-folk, Illusion-folk; Arcnia. Varies by location, TFL.)

Iconic Creatures: ALL OF THEM!!!!!!!! (Both)

Weirdness: Highly technological societies of artificers and artifact creatures. (Both) Plane shaped by unusually high volume of interplanar traffic. (TFL) Spellcasting here is noticeably different from the usual model of drawing mana from lands and casting memorized spells. (Incarnum from D&D; Arcnia) Bizarre landscape with floating, sideways, pillar-shaped, or inverted land masses. (TFL) World overrun, ruled, or recently invaded by iconic creatures, elementals, interplanar creatures, or Phyrexians. (Somehow Mistform got here from Dominaria; Arcnia) Lots and lots of talking animals. Or walking plants with attitude. Or animated land. (All three; Both)
