Eye of Terror - Notable Planets: Altansar - Altansar is a small Aeldari Craftworld that survived the Fall of the Aeldari but was caught in the Eye of Terror following the birth of the Chaos God Slaanesh. Its only escapee was Phoenix Lord Maugan Ra. Ten thousand standard years later in the late 41st Millennium, Abaddon the Despoiler emerged from the insane reality of the Eye of Terror at the head of the 13th Black Crusade. Maugan Ra counterattacked the Eye of Terror to undertake a quest in search of the remains of his people; leaving a silvered trail of soulfire behind him, Maugan Ra eventually found the remains of his Craftworld, and discovered the Asuryani of Altansar had indeed survived millennia within the Eye of Terror. Maugan Ra eventually guided the remnants of his Craftworld out of the Eye and against Abaddon's forces to deny the Despoiler ultimate victory. However, there was no celebration or welcome from the other Craftworlds, for Altansar is regarded with open suspicion and hostility, due to its long exposure to the corrupting influence of the Ruinous Powers within the Eye.Anathrax - Daemon World of Nurgle. During the Abyssal Crusade, the Iron Drakes Chapter made planetfall in force. Though they fought bravely, one by one they were brought low, surrendering their souls to Nurgle. Thus did the Iron Drakes become the Chaos Space Marines of the Grey Death, ready and willing to spread their plague across the stars.Belial IV - Belial IV was a Crone World within the Eye of Terror. During the Abyssal Crusade, the Brothers of the Anvil scoured the tumbled spires of the original Aeldari Empire, only to be brought to battle and eventually captured by the xenos Kabalites that searched the ancient planet for arcane artefacts. After a standard year of nightmarish ordeals in the arenas of Commorragh, the broken remains of the Brothers of the Anvil slaughtered their way back into realspace, where they killed every living thing they found. Shortly after the 13th Black Crusade in 999.M41, the Ynarri led an expedition to Belial IV to capture one of the Crone Swords, battling Daemons along the way.Bubonicus - Daemon World of Nurgle, ruled over by a former mortal Chaos Champion named Lothar, who was later transformed into the Daemon Prince known as Bubonicus.Drakassi - Daemon World of Khorne. This deadly world is wholly dedicated to the Blood God, its most notable feature being a sea of blood which covers the globe, connecting the various cities of the planet. Each city has its own arena where bloody gladiatorial games are held to honour Khorne in its own way. This world is lorded over by a diverse ruling class which includes Daemons, barbarian chieftains, Amazon-like huntresses, Chaos Space Marines and mortal men who try to act like nobility. Their petty squabbling often results in open warfare, but they usually launch raids to other nearby worlds for slaves to fight in the games. Drakassi is lorded over by the supreme ruler known as Lord Ebondrake, a reptilian Daemon Prince, who commands the largest and greatest army on the planet and who sponsors the gladiatorial games.Durrell - Daemon World of Slaanesh.Eidolon - A notable Daemon World contested by the Ruinous Powers. This foul world is ruled by four warring Daemon Princes, who eternally fight for dominance of the contested planet. Blood Angels Captain Leonatos led his band of Exiles into the Eye of Terror and to the world of Eidolon, on a sacred Blood Quest, in order to recover the Blade Encarmine, a sacred sword and Chapter relic.Kathalon - A Daemon World of Khorne, this world is lorded over by the Bloodthirster Vangash'hagash the Ever-Bloody; his world is a great burning lake criss-crossed with arching bridges of brass and bone, over which the legions of Khorne and Tzeentch have fought for aeons.Maeleum - Daemon World within the Eye of Terror. For a time, Maeleum served as the first homeworld of the Sons of Horus Traitor Legion following the immediate end of the Horus Heresy in the early 31st Millennium. The XVI Legion built a massive fortress on the planet and entombed the corpse of their slain Warmaster Horus within it. However, not long after, the Eye of Terror Slave Wars erupted and the Emperor's Children Legion launched a devastating surprise assault on Maeleum, devastating the Sons of Horus' fortress and stealing Horus' corpse in an attempt by the corrupted Apothecary Fabius Bile to clone the dead Warmaster of Chaos and restore the fortunes of the forces of Chaos in the wake of the Imperium's victory in the Horus Heresy.Medrengard - Medrengard is a Daemon World within the Eye that serves as the current homeworld of the Iron Warriors Traitor Legion. Located at the very entrance of the Eye of Terror, Medrengard is a world with a black sun and a white sky, its surface turned into a vast fortress, all trace of its original form lost under mountains of impossibly high towers, its core penetrated by plunging dungeons. Medrengard has been described as a bleak prison world where slaves toil endlessly for the glory of Perturabo. Great Chaos warships are tethered to the tallest fortress towers, wherein reside the Iron Warriors themselves.Oliensis - Oliensis is a Daemon World of Slaanesh which takes the form of a morbidly obese man curled into a foetal ball. During the Abyssal Crusade the Sentinels Chapter made planetfall and began to hunt down and exterminate goat-headed hedonists, but the cacophony of battle stirred Slaaneshi Noise Marines and soon the battle was joined. The raging conflict stirred the living planet itself, which swallowed the combatants into a large chasm. By the time they reemerged, the Sentinels were no longer recognisable, having been transformed into the Corpus Brethren.Plague Planet - The Plague Planet was a Daemon World of Nurgle. The Plague Planet is the home of the Death Guard Traitor Legion. Located at the entrance of the Eye of Terror, it is a world where diseases are the norm and the viridian miasmic clouds that shroud the planet bring contagion and death. The Daemon Primarch Mortarion lords over the pestilent world, having shaped the planet to resemble his former homeworld of Barbarus. Its citizens cower in tiny villages, serving their supreme masters, the Traitor Marines of the Death Guard, who reside in mighty fortress citadels far above all of them. All spacecraft which succumb to plague are eventually drawn, through the Warp, to the Plague Planet, where they become part of the planet's Plague Fleets.Planet of the Sorcerers - The Planet of the Sorcerers, Sortiarius, is a Daemon World of Tzeentch and the home of the Thousand Sons Traitor Legion. Located deep in the Eye of Terror, the Planet of the Sorcerers is lorded over by the Daemon Primarch Magnus the Red. With the fall of his original homeworld of Prospero to the Space Wolves at the start of the Horus Heresy during the Scouring of Prospero, the Crimson King used his sorcerous powers in the final act of his pact with Tzeentch to transfer his beloved and infamous City of Light, Tizca, through the Warp from Prospero to a new planet. In this way, all of the precious (and heretical) knowledge hidden within Tizca's libraries that the Thousand Sons had gathered from all across the galaxy during the Great Crusade was preserved. In 999.M41, The Planet of the Sorcerers was returned to realspace, teleported from the Eye of Terror to a position directly above the remains of the Thousand Sons' lost original homeworld of Prospero. Magnus the Red used the power produced by the deaths of so many during the Siege of the Fenris System to enact the sorcerous ritual that allowed him to return the Thousand Sons to their ancient home.Sicarus - Sicarus is a Daemon World of Chaos Undivided and the homeworld of the Word Bearers Traitor Legion. Sicarus is located somewhere deep within the Eye of Terror. From Sicarus, the veteran Dark Apostles of the XVII Legion who make up the ruling Dark Council watch over the Word Bearers Legion in their Primarch Lorgar's continued absence. The Word Bearers seek to orchestrate the corruption of the Imperium from within at the hands of the various Chaos Cults and witches' covens they sponsor across the galaxy. Beneath a roiling sky of fire and blood, Sicarus is a world completely covered by vast sprawling cathedrals, temples and monuments dedicated to the worship of the Ruinous Powers of Chaos.Sublime - Sublime is a rare sight within the Eye of Terror, a Warp Star in the making, a dying planet frozen in its last moments while hordes of Daemons feed on the essence of everyone who ever lived there or could have been born on this fractured world. Sublime is one of the few precious neutral grounds within the Eye, a non-aligned world where factions sometimes come to parlay and trade, but mostly to indulge their vices. Trade is Sublime's lifeblood and its archeotech markets -- collectively known as Black Golan -- deal with everything, from dreams and new sensations to powerful weaponry and raw materials. To protect these riches, Sublime is surrounded by hundreds of heavily-armed orbital Battle Stations in order to ensure that no outsider faction can interfere with the continual wars Sublime's independent city-states wage on each other. Where other worlds may belong to the Traitor Legions, Daemons or the Dark Mechanicum, Sublime is a haven for Renegades and pirates, be they Aeldari Corsairs, human Renegades, Loxatl or other xenos.Temporia - Temporia is a Daemon World defined by a mind-bending contradiction of cog-plateaus, helical manufactoria and spiralling stairways that clank and span the planet's surface. Temporia is a corrupted Forge World controlled by the Warpsmith Valadrak, who constantly forges massive Daemon Engines for the various Chaos Space Marine warbands within the Eye. At the time of the Abyssal Crusade, this Dark Mechanicus Forge World was invaded by the Knights Excelsior Chapter. During their foray to the surface, the Knights Excelsior soon found themselves surrounded on all sides by massive Daemon Engines. The Space Marines hacked a path back to their dropships, but their escape was for naught, as the vile Warpsmith let loose an electricity-eating Daemon fashioned from tortured Machine Spirits. The Knights Excelsior's dormant warships rebelled against them and their advanced wargear pulsed with static, and the Space Marines were overrun. They were snatched up in the claws of Temporia's Daemon Engines and thrust into the red-hot soul-forges of Valadrak's fortress. Less than a standard year later, the Renegade Space Marines known as the Magma Hounds were seen abroad in the Cadian System, their number almost double that of previous sightings.Ulthwé - A notable Aeldari Craftworld, Ulthwé was caught in the pull of the Eye of Terror, where the Immaterium intersects with realspace. Due to this baleful proximity to the Eye, Ulthwé must be on constant high alert in case of attacks by the forces of Chaos. Constant risk and warfare had hardened this Craftworld's citizens to hardship. Due to the lack of Aspect Warriors on the craftworld, Ulthwé maintains a standing militia known as the Black Guardians, who are more skilled and better-trained than the Guardians of other Craftworlds.Urum the Dead-Alive - Urum is a Crone World, one of the planets formerly inhabited by the ancient Aeldari. When the Eye of Terror first came to be, Urum was ravaged and tainted by the Chaotic energies that escaped from the gigantic Warp Rift, fusing those inhabitants that had not fled in their gigantic Craftworlds to the very soil they used to tread. Urum's ground is now covered with the fused bones of dead Aeldari. Their tormented faces rear out of once elegant walls, supporting beams and statues while the very wind howls with the faint cries of the damned. Although all of its cities now lie in ruin, it is here, far from prying eyes, that the great Apothecary Fabius Bile has established his principal laboratory and cloning facilities, slowly repopulating the world with creatures of his own design. So far none has dared to challenge the Corpsemaster's claim on this world.World of Immortal Sorrows - The poetically-named World of Immortal Sorrows is a Daemon World ruled over by a Daemon of Slaanesh called Elyssar'sirath. Once at the heart of the ancient Aeldari civilisation, it is now a Crone World, where Daemons of the Dark Prince of Chaos torment the souls of the fallen Aeldari under the canopy of a great golden forest through which flow rivers made from the tears of Aeldari children.Xana II - Xana II is a hellish Forge World which lies deep within the Eye of Terror. It is said to be a great stronghold of the Dark Mechanicum. Xana is believed to be a world wholly given over to Daemon-machines and infernal industries, where mills grind flesh and suffering to make the insane visions of its nightmarish masters real, and countless millions are enslaved to work in a world-spanning network of labyrinthine forges, churning out an endless supply of weapons and armaments for the Traitor Legions' Long War. The masters of Xana are ruled by half-Daemon machines themselves, and have long since left the shreds of their humanity behind and are beholden to none -- be they mortal or Chaos God. It is believed Xana II builds the Idolator-class Raider, which has many systems and features of non-Human origin. The Idolator-class Raider is speculated to possess a targeting system difficult for the Adeptus Mechanicus to replicate. They sell or barter their unholy inventions and arms to the highest bidder, be they warlord, demagogue, sorcerer or Daemon Prince without favour, and their coin of exchange is always the same: new "raw material," the flesh and souls of slaves to feed Xana II's endless hunger.
