"They came in their silvery vessels. Impossibly powerful. Mysterious. Then our world was frozen, huge and empty. Life was simple, barbaric, without language, knowledge or civilisation. They changed us. They changed everything. We only know them as the Old Ones. They had the power to move worlds, to bring them closer or to move them away from the eternal heat of the sun. That's what they did, bringing our cold globe back to life. But this unbalanced the other worlds, because everything is connected. Then they moved them too, forming an impossible harmony among the spheres, a perfection that can still be seen today by observing the heavens. See the five children of Asuryan: Charyb, the closest to the sun, only takes 80 days to go around; while Deiamol takes 133 and a third of days; Tigris, 200; our world, 400; and Verdra, 800. Compare this to the five Councilors: Lokratia takes 1,600 days, four of our years; Isharna, 10 years; Loekia, 30 years; Voelia, 150 years; and blessed by the Old Ones -- is an impressive sight even after so many millennia."

Astronomy is the scientific study of the stars, the other planets, the heavens and the Known World's place within the broader cosmos. It is a primary pursuit for the wizards of the Celestial College in the Empire.[4b]

Below can be found a brief overview of many of the heavenly bodies that consume the interest and study of astronomers.

Heavenly Bodies of the Solar System

Andrew Law's unpublished map of the solar system of the Warhammer World


The sun of the solar system containing the mortal world is called Söll.


Children of Asuryan

The star system of the Warhammer World is comprised of ten planets in total. The first five worlds by orbital distance from the sun that comprise the inner system, known as "the children of Asuryan" to the Elves, include:

  • Charyb - The closest planet to the sun, Söll; it makes one revolution around Söll every 80 days.[1a]
  • Deiamol - Deiamol is called "the Burning World." It is described as possessing a deep red surface dotted with countless interlocking circles. It is the second planet from the sun,[4a] and is slightly smaller than Charyb.[4c] It possesses one moon.[1a]
  • Tigris - Tigris revolves around the sun once every 200 days. It it the third planet in the system.[4a] It has two moons.[1a]
  • "The Fated Place" (Warhammer World) - The "Fated Place" is the name given by the Lizardmen and their Old One creators to the known mortal world; it revolves around the sun every 400 days. Two moons orbit the known world, the natural satellite Mannslieb and an unnatural moon, Morrslieb, born from a massive fragment of viridian warpstone that was flung into orbit of the world after the collapse of the Polar Gates and the Coming of Chaos. It was to this world that the Old Ones first came in their silvery ships. It was a far colder planet when those starfarers first arrived; through their incredible understanding of arcane artifice and the technologies available to them, they moved the world closer to its sun, dramatically warming its climate and making it more hospitable for the mortal races they would create upon it, including the Slaan, Lizardmen, Elves, Dwarfs and Men.[1a]
  • Verdra - The fifth planet of the system is described as a green sphere that possesses visible continents. It makes one revolution around the sun every 800 days.[4a] It possesses one moon.

The Councillors

The last five worlds of the outer system are called "the Councillors" and include:

  • Lokratia - Lokratia, the sixth world of the system, is a planet whose surface is covered with meteor scars. It makes one revolution around the sun every 1600 days. It is described by astronomers as being ash-grey in colour, with orange lines stretched across its surface.[4a] It has seven moons.[1a]
  • Isharna - Isharna is the seventh planet to orbit the sun and is described as "a mass of hot gasses" that is "striped with red and orange." Its orbital period around the sun is 4000 days. It has thirteen moons.[1a]
  • Loekia - The eighth planet, Loekia, has an orbital period of 12,000 days. It has six moons.[1a]
  • Voelia - The ninth planet from the sun, Voelia, takes an incredible 60,000 days to make one revolution around the sun. It has fourteen moons.[1a]
  • Obscuria - Obscuria, the tenth and most distant world in the system from the sun, is described as being deathly pale apart from three bruised smudges, a smattering of tiny black pinpricks, and covered with ice. Its very existence is disputed in the Empire and deduced only from theoretical arguments (though according to Bartolomi Kereveld, only if they don't understand calculus).[4a] With that said, the Celestial College of wizards has always known Obscuria was "somewhere" out in the void, largely due to what Kereveld called a "doppler effect" that it makes in the magical field surrounding the solar system. Until Kereveld's expedition to Lustria was made, the Celestial College had never been able to accurately calculate its ellipse.[4b] It has one moon.[1a]

Moons of the World

  • Mannslieb - The world's natural moon, as opposed to its companion in the sky Morrslieb, which was brought into being by the unnatural events surrounding the Coming of Chaos. Also known as the "white moon," Mannslieb keeps a regular 25-day rotational cycle around the world, from one full phase to another.[1]
  • Morrslieb - Morrslieb is the second green moon of the world, and the dark twin of Mannslieb. It has an erratic cycle, unpredictably appearing smaller or larger in the sky. In times of disaster, some claim to see a mocking, twisted face appear on its surface. Morrslieb heralds great misfortune to many cultures when it appears closer to the world. Morrslieb is actually a massive portion of Warpstone, condensed and solidified magical energy, that was flung from the Realm of Chaos following the collapse of the Old Ones' Polar Gates and the Coming of Chaos to the world.[1]

Stars and Constellations

Many inhabitants of the Empire believe that the stars or constellations one is born under have a hand in determining one's fate.[2a]

Comets and Meteors

  • Comet of Cassandora - Sometimes described as a "meteorite" which is called via magic.
  • Great Maw - Speculated to have originated in a warpstone comet which impacted the Warhammer World, becoming a god of eternal hunger and tormenting the Ogres, turning a once green area into a colossal crater.
  • Loremaster Eldrick Starfire - A celestial body whose trajectory has been calculated.[1a]
  • Twin Tailed Comet - A portent of important/dangerous times, noted by all races but especially revered by followers of Sigmar and Sotek.

Notable Astronomers


In the star chamber of Ytzel Cho, it is shown that the solar system dwells within a spiral galaxy. The star chamber is also able to determine the appearance of Morrslieb down to the day.[4c]

Andrew Law (AKA Hapimeses) created a map of the Warhammer World's solar system for Tome of Salvation, a Warhammer Fantasy Roleplay 2nd Edition supplement, but it was cut from publication. Andrew used the Black Library novel The Burning Shore as a key reference to create this map, as it named the entire solar system and gave some details.[1a][4]
