The planes of the Inner Sphere form the heart of the cosmos. They're the home of mortal life, the focus of divine attention, the source of mortal souls, and the origin point of the great cycle of quintessence that fuels the motions and stability of reality itself. Arranged in a nested series of shells, like layers of an onion, the planes of the Inner Sphere include, from outer to inner: the elemental planes of
fire,
earth,
metal,
water,
wood, and
air; the mortal galaxies of the Universe; and at the very core of this cosmological ensemble, the raw forces of creation and destruction of
Creation's Forge and
the Void overlap the
Universe.
