The 507th level of the Abyss, Occipitus is unusual even amongst the intensely diverse topography of this chaotic plane. Millennia ago, it was a actually part of Celestia, or Heaven. Then it was the site of a tremendous battle between celestial armies and the army of Adimarchus, a rebel angel. In order to purge Celestia of Adimarchus's corrupting influence, the Gods of Light literally carved out the ground beneath his feet, sending plains and mountain ranges alike hurtling out of Heaven.
When Occipitus landed in the Abyss, it became a twisted, decimated echo of its former site. Although it was corrupted by Adimarchus's evil (and the evil of the demons who came to inhabit it), the plane retained small shards of positive energy reminiscent of its former glory; these shards often manifest themselves as "flashbacks," briefly and tantalizingly transforming the environment into something beautiful and serene.
Most of the time, however, Occipitus is just as hideous and inhospitable as the rest of the Abyss. Its environment has a disturbingly organic motif: flora resembles hair and bones, lakes are filled with ulcerous blood, and the ground itself is the colour and texture of decaying flesh. High above the ground, the air seethes with semi-sentient blobs of acidic protoplasm. These blobs surge continuously out of the "eye" of Occipitus's most distinctive landmark: a bone-white mountain in the shape of a smashed skull.
When Adimarchus, the former lord of the plane, was imprisoned in the planar prison of Carceri, he left behind him a series of magical tests -- collectively called the Test of the Smoking Eye -- to determine which, if any, of his claimaints deserved to inherit Occipitus. Pip has recently completed the final test, and has been granted control over the plane's physical reality.
The Cathedral of Feathers: This was a cathedral in Celestia and now magically switches between two forms - one light, and one dark. This was the site of the first test of the smoking eye. It contains a library of floating books, and a chamber that was once home to a spider demon.
Plain of Cysts: This was where many angels were slain in the battle so long ago. Occipitus has formed cyst/cocoons around the fallen. Treasure hunters come here to loot the dead angels, but are stymied by the many teleportation traps within.
Ossaic forests: Formed of a chalky, crumbling substance, the ossaic forests are collections of gently curving columns that pierce the spongy surface of the layer.
Fibrous forests: Some parts of Occipitus have house-sized tangles of fleshy ropelike plants that feed off of the layer's surface. these tangles of fibers slowly attempt to consume creatures who stay in one place too long.
Plain of Ulcers: About a half mile from The Skull is an open plain dotted with pools of what look to be blood. Some of the pools spew the blood from the center like a geyser or fountain. Pip has some of the demons using the pools to create Abyssal Blood Wine.
The Skull: At the center of Occipitus is a massive skull half-embedded in the ground. A magical blaze rages in one eye, which may be the source of the strange fire plasma clouds which hover low over the realm. Inside is a throne room guarded by a clay golem, and a Nexus Room which contains a nexus of evil eldritch power.
Pip makes wine from grapes that grow in the blood pools of Occipius. There's a goo, short summary on how to make wine here.
× Grapes must be picked when they are just ripe
× Juice is squeezed out (stems can be left in for a more tannish flavor)
× Ferment either in a metal vat (crisp flavor) or an oak barrel (for a mellow flavor)
× Add yeast
× Wait 3 to 4 weeks
× Remove skins and stems, make sure the temperature is just right
× Age the wine in barrels - the wine absorbs some of the oak of the barrels for flavor
× Store for 9 months to 2 1/2 years
× Put into bottles, age longer if you like
