THE PLANE OF EXOS
Exos in the Norstari language, the human tongue of the Jeweled North, translates to "the plane of the exiled." This name refers to the Father-God Yogoroth's banishment to Exos from another reality during the Void Age. Since his arrival to Exos, it acts as the material plane, the home to the Blood Gods and the birthplace of the mortal races. Exos is composed of...
The Sundered Realms
The Blood Gods made the world Haven to serve as their sanctuary. They resided on Haven, attended by their mortal servants until the Sundering. Shattered by the powers of Hell which invaded during the Demon Age, Haven was torn to pieces. Now, the remnants of Haven are nothing but pieces of floating earth, known as world-shards, such as Asora, Iazstraban and Ogiama, at the center of Exos.
The outer limits of Exos' creation, far beyond the Sundered Realms are referred to as the Outlands. These starless worlds absent of the Blood Gods influence are alien and distant. In their darkness, devoid of starlight, the countless worlds of the Outlands have devolved into madness, giving rise to the Uldrax. Even with the use of shard-ship technology the Outlands are unknowable and virtually unreachable without the use of Cosmic magic, portals or teleportation.
The Elemental Planes
Long before the Sundering the Blood Gods imprisoned the Elemental Lords of Exos, the Basal Colosum, within demi-planes known as the Elemental Planes.
THE BLACK DEPTHS
This is the plane of Suron, the Basal Coloss of Water. Observers of this plane refer to it is an endless salt-water sea of dizzying depths with pockets of freshwater, underwater caves and small islands.
THE SEARING EXPANSE
The Basal Coloss of Flame, Pyrok, resides on the Searing Expanse. His home is dominated by vast plains of living flame, rolling clouds of smoke and churning bodies of magma.
THE SPIRALING VAULTS
Darkness in all too commonplace within the Spiraling Vaults, the Elemental Plane of Earth. The Basal Coloss Euron rules here among the inumerable caverns and earthen tunnels that weave across his realm.
THE OPEN GALE
The Open Gale is a bottomless plane of wind currents, floating palaces and continent wide clouds with hidden secrets kept within. Wiror, the Basal Coloss of Air rules here among the horizonless skies.
There are two transitory reflections of Exos which must be travelled to cross the Axiom Verge: Luzos and Exos. Rather than being planes in themselves, the Echoes are just mirrors of Exos which aligned, but sepererate fro the material plane.
Luzos is home to those entities known as celestials and is sometimes referred to as the "Lands Between Light." This Echo is a plane which appears as Exos, just as the Blood Gods had originally made it. Within Luzos, Haven still appears as an intact world, with a sun and an infinite amount of stars in the night sky. One must pass through Luzos in order to cross the Axiom Verge into the High Heavens. Luzos can be reached without Cosmic magic by entering places of intense natural light and reflection.
The spirits known as the Collectors call Oscuros, the "Shadow Lands" their home. These entities harvest the souls of the dead in order to auction them off to either the demons of the Infernal Circles or the angels of the High Heavens. Oscuros is a demented reflection of Exos cast in eternal shadow and plagued by the restless undead and the occasional demon raiding party. One must pass through Oscuros in order to cross the Axiom Verge into the Infernal Circles. The Shadowlands can be reached without Cosmic magic by entering places of deep natural darkness.
The Axiom Verge
The boundary that separates the material plane from the realms of Titania and Hell, lays at the edge of Exos' Echoes. This border, the Axiom Verge, is not necessarily a physical location, but more a figurative term relating to the act of crossing itself. By bridging the Axiom Verge, one steps into the planes at the fringes of Exos' reality.
THE HIGH HEAVENS OF TITANIa
The winged angels of the Angelic Host are the undisputed rulers of the High Heavens. Titania is a realm of three immense hollow rings, layered within each other and whose inner surfaces being the habited regions. Amongst the cloud touched rings of the High Heavens, the Archangels make their seats of power, ruling in concert to protect the mortal races and defeat the forces of Hell.
THE INFERNAL CIRCLES OF HELL
The plane of Hell is composed of nine layers of varying hostile landscapes, each ruled by a Demon Prince and floating within the epicenter of a swirling tempest. The three most central rungs of Hell's layers expand out into the horizon infinitely with fiefdoms that pay homage to, while also secretly plotting against, one of the Prime Evils.
The Severed Beyond
The forces which banished Yogoroth to Exos in the prehistoric past, also did their best to keep his erratic and destructive personality bound within the material plane for eternity. They did this by cutting Exos' connection to the greater Multiverse, thus isolating reality from the plethora of alternate dimensions and planes within the Severed Beyond.
