Hybris: an ancient, abandoned city of ornate towers and interlocking balconies and catwalks. The artwork is oddly stylized and mostly consists of aquatic creatures, although the city itself is land-locked. It is now inhabited by a rabble of refugees from various realms. Its portals are unstable and rarely allow more than a handful of folks to pass through before changing the destination that they lead to.
Korth: a decaying jungle realm whose deity (the goddess Allassarra) recently perished. Inhabited mostly by her surviving subjects, but the realm is gradually becoming unlivable without her magics to sustain it.
Choronos: a blasted wasteland ruled by the mad god Lalindiel and his Terrible Ones. Widely shunned.
Myros: the home realm of the Brutes, the demons lead by Benefor the Merciless.
The Hells: several closely tied realms ruled by Xualia the Cruel and her Fiends.
Arborelle: a realm of great forests. Ruled by the goddess Nahura and her Sandili.
Infernus: the fiery, volcanic realm inhabited by the Salamanders. No true deity, just the massive mana font they call Illiu.
Oceanus: the water world ruled by the Undines. Ruled by a pair of deities: Ahmn and Mna.
The Bright Lands: a group of tightly connected realms ruled by the pantheon of gods called the Lords of Light.
