ONE POSSIBLE COSMOLOGY
In this conception, the Ethereal Plane extends beyond Earth to the Moon, but no further. The Astral Plane extends throughout the entire universe, to the borders of the Empyrean Heaven.
All of the planes (i.e. planets) in this cosmology other than the Empyrean Heaven are self-contained spheres. Heaven is infinite.
EARTH AND THE MOON (MATERIAL PLANE)
Earth and the Moon are the Material Plane, the center of the universe. The Moon differs from Earth only in that it is mildly-chaotic. They define what is considered normal. The Material Plane has the following traits:
• Normal gravity.
• Normal Time
• Alterable morphic.
• No Elemental or Energy Traits (specific locations may have these traits, however)
• Mildly neutral-aligned (mildly chaos-aligned for the Moon).
• Normal magic.
THE ETHEREAL PLANE
The Ethereal Plane is coexistent with the Material Plane and the plane of Luna. The Material Plane itself is visible from the Ethereal Plane, but it appears muted and indistinct, its colors blurring into each other and its edges turning fuzzy.
While it is possible to see into the Material Plane from the Ethereal Plane, the Ethereal Plane is usually invisible to those on the Material Plane. Normally, creatures on the Ethereal Plane cannot attack creatures on the Material Plane, and vice versa. A traveler on the Ethereal Plane is invisible, incorporeal, and silent to someone on the Material Plane.
The Ethereal Plane is mostly empty of structures and impediments. However, the plane has its own inhabitants. Some of these are other ethereal travelers, but the ghosts found here pose a particular peril to those who walk the fog.
It has the following traits.
• No gravity.
• Alterable morphic. The plane contains little to alter, however.
• Mildly neutral-aligned.
• Normal magic. Spells function normally on the Ethereal Plane, though they do not cross into the Material Plane. The only exceptions are spells and spell-like abilities that have the force descriptor and abjuration spells that affect ethereal beings. Spellcasters on the Material Plane must have some way to detect foes on the Ethereal Plane before targeting them with force-based spells, of course. While it’s possible to hit ethereal enemies with a force spell cast on the Material Plane, the reverse isn’t possible. No magical attacks cross from the Ethereal Plane to the Material Plane, including force attacks.
PLANE OF SHADOW
The Plane of Shadow is a dimly lit dimension that is both coterminous to and coexistent with the Material Plane. It overlaps the Material Plane much as the Ethereal Plane does, so a planar traveler can use the Plane of Shadow to cover great distances quickly.
The Plane of Shadow is also coterminous to other planes. With the right spell, a character can use the Plane of Shadow to visit other realities.
The Plane of Shadow is a world of black and white; color itself has been bleached from the environment. It is otherwise appears similar to the Material Plane.
Despite the lack of light sources, various plants, animals, and humanoids call the Plane of Shadow home.
The Plane of Shadow is magically morphic, and parts continually flow onto other planes. As a result, creating a precise map of the plane is next to impossible, despite the presence of landmarks.
The Plane of Shadow has the following traits.
• Magically morphic. Certain spells modify the base material of the Plane of Shadow. The utility and power of these spells within the Plane of Shadow make them particularly useful for explorers and natives alike.
• Mildly neutral-aligned.
• Enhanced magic. Spells of shadow are enhanced on the Plane of Shadow. Such spells are cast as though they were prepared with the Maximize Spell feat. Shadow conjuration and shadow evocation spells are 30% as powerful as the conjurations and evocations they mimic (as opposed to 20%). Greater shadow conjuration and greater shadow evocation are 70% as powerful (not 60%), and a shades spell conjures at 90% of the power of the original (not 80%).
• Impeded magic. Spells that use or generate light or fire may fizzle when cast on the Plane of Shadow. Spells that produce light are less effective in general, because all light sources have their ranges halved here. Despite the dark nature of the Plane of Shadow, spells that produce, use, or manipulate darkness are unaffected by the plane.
THE ASTRAL PLANE
The Astral Plane is the space between the planes. When a character moves through an interplanar portal or projects her spirit to a different plane of existence, she travels through the Astral Plane. Spells that allow instantaneous movement across a plane briefly touch the Astral Plane.
The Astral Plane is a great, endless sphere of clear silvery sky, both above and below. Occasional bits of solid matter can be found here, but most of the Astral Plane is an endless, open domain. Both planar travelers and refugees from other planes call the Astral Plane home.
The Astral Plane has the following traits.
• Subjective directional gravity.
• Timeless. Age, hunger, thirst, poison, and natural healing don’t function in the Astral Plane, though they resume functioning when the traveler leaves the Astral Plane.
• Mildly neutral-aligned.
• Enhanced magic. All spells and spell-like abilities used within the Astral Plane may be employed as if they were improved by the Quicken Spell feat. Already quickened spells and spell-like abilities are unaffected, as are spells from magic items. Spells so quickened are still prepared and cast at their unmodified level. As with the Quicken Spell feat, only one quickened spell can be cast per round.
MERCURY (ELEMENTAL PLANE OF EARTH)
Mercury is a solid sphere of rock and metal burrowed through by a multitude if tunnels and caverns. An unwary and unprepared traveler to Mercury may find himself entombed within this vast solidity of material and have his life crushed into nothingness, his powdered remains a warning to any foolish enough to follow.
Despite its solid, unyielding nature, Mercury is varied in its consistency, ranging from soft soil to veins of heavier and more valuable metal.
Mercury has the following traits.
• Earth-dominant.
• Enhanced magic. Spells and spell-like abilities that use, manipulate, or create earth or stone are both empowered and extended (as if the Empower Spell and Extend Spell metamagic feats had been used on them). Spells and spell-like abilities that are already empowered or extended are unaffected by this benefit.
• Impeded magic. Spells and spell-like abilities that use or create air (including spells that summon air elementals or outsiders with the air subtype) are impeded.
VENUS (POSITIVE ENERGY PLANE)
Venus is a lush world of brilliant, almost blinding color and overgrown vegetation and animals. Some area of the plane are so fertile that entering them can actually cause a person to explode with life.
Venus has the following traits.
• Normal gravity.
• Minor positive-dominant. Some regions of the plane have the major positive-dominant trait instead, and those islands may be inhabited by various divinities of fertility and life.
• Enhanced magic. Spells and spell-like abilities that use positive energy, including cure spells, are maximized (as if the Maximize Spell metamagic feat had been used on them). Spells and spell-like abilities that are already maximized are unaffected by this benefit. Class abilities that use positive energy, such as turning and destroying undead, gain a +10 bonus on the roll to determine Hit Dice affected.
• Impeded magic. Spells and spell-like abilities that use negative energy (including inflict spells) are impeded.
MARS (PLANE OF NEUTRALITY)
Mars is an earth-like plane dedicated to neutrality in the war between Law and Chaos. It is a small sphere and taken up by red, sandstone hills, shallow, salty seas, lowlands of red, tuberous plants watered by vast canals and gleaming, ancient cities slowly falling into ruin. The various people of Mars are warriors who glory in combat.
Mars has the following traits.
• Light gravity.
• Strongly neutral-aligned. Lawfuls and chaotic suffer a -2 penalty to reaction checks and to intelligence- and wisdom-based checks.
• Limited magic. The following spells operate normally on Mars: Detect thoughts (ESP), xxx. All other spells fail to operate here.
• Flowing time. Time passes more quickly on Mars than the Material Plane. A year spent on Mars corresponds to a day on the Material Plane.
SUN (ELEMENTAL PLANE OF FIRE)
Everything is alight on the Sun. The ground is nothing more than great, evershifting plates of compressed flame. The air ripples with the heat of continual firestorms, and the most common liquid is magma, not water. The oceans are made of liquid flame, and the mountains ooze with molten lava. Fire survives here without need for fuel or air, but flammables brought onto the plane are consumed readily.
The Sun has the following traits.
• Fire-dominant.
• Enhanced magic. Spells and spell-like abilities with the fire descriptor are both maximized and enlarged (as if the Maximize Spell and Enlarge Spell had been used on them). Spells and spell-like abilities that are already maximized or enlarged are unaffected by this benefit.
• Impeded magic. Spells and spell-like abilities that use or create water (including spells that summon water elementals or outsiders with the water subtype) are impeded.
JUPITER (ELEMENTAL PLANE OF AIR)
Jupiter is a giant spheric plane of air. At the heart of Jupiter there is a core of iron and adamantine, and there are other bits of solid ground and water vapor floating amid the endless, roiling skies of Jupiter.
Jupiter is the home of all manner of airborne creatures. Indeed, flying creatures find themselves at a great advantage on this plane. While travelers without flight can survive easily here, they are at a disadvantage.
Jupiter has the following traits.
• Subjective directional gravity. Inhabitants of the plane determine their own “down” direction. Objects not under the motive force of others do not move.
• Air-dominant.
• Enhanced magic. Spells and spell-like abilities that use, manipulate, or create air are both empowered and enlarged (as if the Empower Spell and Enlarge Spell metamagic feats had been used on them).
• Impeded magic. Spells and spell-like abilities that use or create earth (including spells that summon earth elementals or earth-based outsiders) are impeded.
SATURN (PLANE OF CHAOS)
Saturn is a plane infused with chaos, and therefore quite alien to most folk of the Material Plane. It is covered by all manner of fascinating land-scapes, including ashen plains cut by streams of mercury, swamps of sentient ooze, thickets of mineral plants like sheaves of swords and towering mountains of vapor, all under a greenish-black sky illuminated by the plane’s wondrous rings from which ioun stones are plucked.
Saturn has the following traits:
• Strongly chaos-aligned. Lawfuls suffer a -2 penalty to reaction checks and to intelligence- and wisdom-based checks.
• Wild magic.
NEPTUNE (ELEMENTAL PLANE OF WATER)
Neptune is a sea without a floor or a surface; an entirely fluid sphere lit by a diffuse glow. It is one of the more hospitable of the Inner Planes once a traveler gets past the problem of breathing.
The eternal oceans of this plane vary between ice cold and boiling hot, between saline and fresh. They are perpetually in motion, wracked by currents and tides. The plane’s permanent settlements form around bits of flotsam and jetsam suspended within this endless liquid. These settlements drift on the tides of the plane of Neptune.
Neptune has the following traits.
• Subjective directional gravity. The gravity here works similar to that of the Elemental Plane of Air. But sinking or rising on the Elemental Plane of Water is slower (and less dangerous) than on the Elemental Plane of Air.
• Water-dominant.
• Enhanced magic. Spells and spell-like abilities that use or create water are both extended and enlarged (as if the Extend Spell and Enlarge Spell metamagic feats had been used on them). Spells and spell-like abilities that are already extended or enlarged are unaffected by this benefit.
• Impeded magic. Spells and spell-like abilities with the fire descriptor are impeded.
URANUS (PLANE OF LAW)
Uranus is the opposite of Saturn, a plane of law and perfection. Uranus has the same landscapes as the Material Plane, but they are each perfect and slightly angular, often repetitious, as though made by the will of a single artist. The skies and landscapes of Uranus all carry a metallic hue – warm coppers, brilliant silvers and dazzling golds.
Uranus has the following traits:
• Strongly law-aligned. Chaotics suffer a -2 penalty to reaction checks and to intelligence- and wisdom-based checks.
• Static. Uranus cannot be altered by visitors.
• Timeless. Time does not flow on Uranus.
PLUTO (NEGATIVE ENERGY PLANE)
To an observer, there’s little to see on Pluto. It is a dark, empty place, an eternal pit where a traveler can fall until the plane itself steals away all light and life. Pluto is the most hostile of the planets, and the most uncaring and intolerant of life. Only creatures immune to its life-draining energies can survive there.
Pluto has the following traits.
• Subjective directional gravity.
• Major negative-dominant. Some areas within the plane have only the minor negative-dominant trait, and these islands tend to be inhabited.
• Enhanced magic. Spells and spell-like abilities that use negative energy are maximized. Spells and spell-like abilities that are already maximized are unaffected by this benefit. Class abilities that use negative energy, such as rebuking and controlling undead, gain a +10 bonus on the roll.
• Impeded magic. Spells and spell-like abilities that use positive energy, including cure spells, are impeded. Characters on this plane take a –10 penalty on Fortitude saving throws made to regain lost levels from a life drain attack.

Quauor? Eris (formerly Xena)?
ReplyDeleteI really like what you're doing here, though I'd either stop at Saturn or keep working outward. Maybe I'd even play up the uncertainty of the outer spheres, like they're unknowable Schroedinger zones until you go there...
Normally I would stop at Saturn and then maybe use the stars in the firmament as demi-planes, but in this case I wanted to cover all the basic planar bases to show how they might work in the rules.
