Most Athasians know nothing of the worlds and
planes that exist beyond their own. Very few scholars
have studied such topics at length, and their writings
are locked away in the vaults of the sorcerer-kings.
All Athasians know the night sky and its familiar
constellations, and many peoples assign different
meanings to the motions of the stars and planets.
Athas has two moons, Ral and Guthay. Ral, a mottled
green in color, is the closer of the two. Sages who have
scried Ral report that it is covered in great green seas
and mountain-islands of dizzying heights. Guthay,
the smaller and more distant moon, is a golden orb
mantled in steaming mists beneath which lie scarlet
jungles and marshy seas. Stories tell of ancient moongates on Athas that lead to both Ral and Guthay, but
they function only at unpredictable intervals.
Travelers in the wastes tell of the Lands Within
the Wind, an otherworld of magic and enchantment
that exists alongside the material world. Known in
some ancient texts as “the Feywild” or “the Kingdoms Invisible,” this otherworld seems to be an echo
or reflection of Athas. It is absent from most places
around the planet, but pockets of this realm lie in
remote deserts and mountains, especially the Forest
Ridge. These pockets are small; scholars believe that
the total amount of the plane remaining in existence,
combining all fragments scattered across Athas,
would fit inside the walls of Tyr. The Lands Within
the Wind are home to the eladrin, an elflike race of
mysterious powers. A traveler could walk right past
an eladrin palace and never see it because it lies in
the other plane instead of on Athas.
The Gray is another echo of Athas, an otherworld
of shadows and ghosts. In this realm, the restless
spirits of the dead linger amid the haunted ruins of
great cities. Some sources call this otherworld “the
Shadowfell” or “the Plane of Shadow.” Like the Lands
Within the Wind, the Gray is home to strange and
powerful creatures, including mighty shadow giants,
fearsome nightmare beasts, and a race of devils that
traveled to the Gray when the connection between
their home plane and Athas withered. Unlike the
eladrin of the fey realm, the denizens of the Shadowfell are much more hostile to mortals who venture
into their domain.
Many erudite thinkers believe that the Gray acts
as a barrier between Athas and other realms beyond,
and that long ago, the domains of the gods could be
found in starry seas beyond the Gray. But the Astral
Sea has been empty for ages. No godly domains
remain within reach of mortal travelers, and the
easy connections between the plane and Athas have
been severed. The few Athasians who have journeyed
beyond the Gray into the depths of the Astral Sea
(usually agents of the sorcerer-kings, dispatched to
seek long-lost treasures) have found little more than
desolate ruins and terrible abominations.
Underlying the rest of existence is the Elemental
Chaos, a vast, churning realm from which all the
energy and elements of the world were formed. Some
sources call this realm “the Elemental Planes” or “the
Inner Planes.” In cosmological terms, Athas is close
to the Elemental Chaos, and vortexes such as volcanoes, sand gyres, and desert flats known as “anvils”
link the planet to corresponding parts of the seething
realm. Elemental influences grow steadily stronger
and more chaotic as one travels farther away from the
Tyr Region, suggesting that the presence of civilization or natural life holds true elemental power at bay
(or that in the distant past, the region was shielded
from unchecked elemental manifestations). In the
depths of the Elemental Chaos lies the Abyss, from
which come the demons that plague Athas when they
are summoned by reckless rituals or planar rifts
