1001 Plane Ideas

[Einherjar101]

Recently some friends and I had the idea of trying to do a planes jumping game in which each of us will take it in turns to dm a different plane (sort of like sliders I guess).

And obviously this got me thinking about cool ideas for planes.

So what are your favourite plane ideas or published scenarios?

1. An organic plane with sentient plants and flesh like cave systems (think the flesh chamber in american mcgee's alice).

2. Admittedly this would be a pain to DM:

A plane made of a great mass of spheres from a few meters across to a few hundred. They're always moving slowly, they never collide. Inside a sphere is normal but it's impossible to either walk or fly while outside a sphere. The only means of locomotion are teleportation and jumping to another sphere. (Note that if the sphere is made of something soft enough you can tunnel, albeit carefully as you'll have to dig the ground away from under your feet and fall in at least a little bit.)

3. A plane that is constantly trying to eat you. A mouth will open under you and try to digest you. The damage is low enough that rescue is feasible. It's slow, though, it takes the plane a minute to position the mouth. That means safety comes from always moving. You'll have to sleep off the ground somehow--trees or something like a magnificent mansion.

4) A weak, purplish sun that supports no plant life hangs in the sky. This plane consists of dark, rugged lands inhabited soley by carnivores and scavengers horrid to behold. Jaded planeswalkers venture here when big-game hunting gets too boring elsewhere.

5) People with purple skin and people with orange skin inhabit this plane, and though they share the same spaces, they cannot perceive each other at all and are unaware of each others' existence. The actions made by unseen people are blamed on ghosts, spirits, faulty memory or misperceptions. Travelers from other planes, of course, can see both races perfectly well.

6) World where water is breathable and the air will drown terrestrial creatures, vice versa for aquatic creatures. Other than that detail, the physics for both underwater and abovewater are unchanged. Octopi are uncontested masters of both the dry land and the water.

7) A plane where magic works quite differently:

Spell slots are regained in an hour instead of a day and are automatically filled with whatever you had in them last, you only prepare spells if you want to change them.

However it takes two people to cast a spell. Both must cast the spell with exactly the same details (different classes may work together so long as it's the same type of spell for both of them) and it must be valid for both of them. Both must supply half of any components needed, or complete components in the case of something that isn't divisible. (Thus, for example, both casters must eat a spider when casting spider climb.) If the range is self the spell applies to both of them, if the range is touch then both must touch the *SAME* target.

Teams (normally romantically-bonded couples) that work together for a long time raise their caster level by one for every ten years they have been working together. This applies only to effects, it doesn't grant slots they would not otherwise have.

8) A plane where the dead always rise 24 hours after death. They come back as an undead with the number of HD that they had class levels in life, intelligent casters retain their casting. They retain their alignment.

However they are in a slightly different dimension than the living. All objects from the world show up in this shadow world but they can only be manipulated by the living although they affect the undead normally. (Thus a wagon can run over an undead inflicting normal damage.) While spellcasting works normally material components are basically unobtainable--the only way they could be obtained is by someone plane traveling and bringing them back. Those who need spellbooks will have to make do with what they can find open (unless they can bring one back by planar travel).

9) This is a seemingly endless jungle, its canopy yielding only shafts of yellow light. Those who travel long enough realize that they are constantly going in circles. The remains of planeswalkers, insane, starved or both after finding themselves trapped in this balmy world, lie amidst the detritus. To make matters even worse, a monkey appears every now and again and squeals taunts at hapless wanderers. The secret to escaping the plane is to go up. The plane's sun is in fact a portal to the elemental plane of fire that operates for half of a "day", and it lies not far above the highest tree...

10) A plane of mostly desert and rock. Among its inabitance is a reptilian like race with long legs and known for their agility and acrobatics. This makes them particularly tough to fight and many a planes walker has discovered that ingenious methods have to be applied when combating these creatures. Many of them use some forms of djinn magic and this can be seen most spectacularly in their great settlements who's walls are like waterfalls of sand cascading upwards.
Another species of this plane are the large insectile hives that borrow through the rock underground. While their tunnelers have been known to cause sink holes and collapses and their forgers and solders are fierce and dangerous it has been discovered that their workers produce a type of nectar that the reptilian race use as one of their main sources of nourishment in this arid environment.

11) A plane of unimaginably strong gravity (use Strong Gravity rules but multiply all numeric values by 10, including penalties to skill checks, falling damage rolls, and maximum falling damage). The plane also has the Flowing Time trait (one hour on the Material plane equals one round on this plane). The surface of the plane is a vast wilderness of metallic bedrock having the appearance of polished silver, with little variation--a few hills, perhaps one or two even taller than a human, and the occasional rut or crevice no deeper than knee-height, but otherwise utterly featureless. The only major sources of light in this realm are two pillars of brilliant scintillating light streaming from (or into?) the sky at opposite ends of the horizon, one slightly thinner and dimmer than the other. Most visitors to this plane who have survived to report on the matter have arbitrarily chosen one pillar to designate "north" and the other "south", as these phenomena seem to be continually stationary.

A perpetually nighttime sky awash in faint stars wheels overhead so fast that any given star rises and sets in mere seconds, even seeming to change color as it moves across the sky, only to come round again less than a minute later. Most cannot tolerate this twisting of the sky for long, and observers begin to experience increasing nausea and vertigo until they shut their eyes to it or keep their gaze on the ground in front of them.

There is a 1% each round that the plane experiences a sudden but powerful forcequake which ripples visibly across the terrain within range of the PCs, leveling out a small section of it, and emanating a tremendous shock wave of force energy in all directions.

Despite the appearance of being some kind of cold, dead desert, the surface of this plane actually radiates extreme amounts of "black fire" (Fire-Dominant elemental trait).

The surface of the plane is a vast wilderness of bedrock having the appearance of polished silver, with little variation--a few hills, perhaps one or two even taller than a human, and the occasional rut or crevice no deeper than knee-height, but otherwise utterly featureless. The ground itself is unnaturally cold. The only major sources of light in this realm are two pillars of scintillating light streaming from (or into?) the sky at opposite ends of the horizon.

You're describing the surface of a neutron star. The "mountains" might be a centimeter tall:

I also want to know what sort of strength score is needed to survive there!
