Places on Arda

The Keléstia - A cycle of seven linked worlds

Prime Material Plane


The Phlogistan is the vast explosive nothingness between places. It has its own flows and tides, which usually change too slowly to be noticed.

Only expert Spelljammer pilots can safely navigate the currents between the Crystal Spheres that dot it like jewels, each containing a sun and its attendant worlds.

Spelljammer. org - the great source on Crystal Spheres, the Wildspace, and the strange ships and sailors who travel between.

Flow Map of the Phlogistan

Eä is the Quenya name for the universe and has remained unchanged from Sindarian to Grey Elf languages. The word for to be. Thus, Eä is the World that Is, as distinguished from the World that Is Not.

ArdaSpace Sphere

  • Anor -the Sun
    • Elemmire - the innermost and smallest planet in the solar system too small for its gravity to retain any significant atmosphere over long periods of time
    • Earendil’s Star - the second-closest planet to the Sun, orbiting it every 224.7 Arda days. It is the brightest natural object in the night sky, except for the Moon, reaching an apparent magnitude of −4.6. Because Earendil’s Star is an inferior planet, from Arda, it never appears to venture far from the Sun. Earendil’s Star reaches its maximum brightness shortly before sunrise or shortly after sunset, for which reason it is often called the Morning Star or the Evening Star.
    • Arda - Arda Marred - the world as it is, including everything in the skies around it.
  • Carnil - the fourth planet from the Sun in the Solar System. It is also referred to as the “Red Planet” because of its reddish appearance as seen from Arda.

    • At least 63 natural satellites orbit Alcarinque. Of these, 47 are less than 10 kilometres.
    • The four largest moons of Alcarinque are known as the “Eldar moons” !?!? Staff of Power !?!? Eltan makes a connection!
  • Lumbar - the sixth planet from the Sun and the second largest planet in the Solar System
  • Luinil - the seventh planet from the Sun, is the third largest and fourth most massive planet in the solar system.
  • Nenar - the eighth planet from the Sun in the Solar System.
  • Valacirca - The Burning Briar, The Sickle of the Valar, the seven stars set in the sky by Varda as an enduring warning to Melkor and his servants.

Other Planes

Harn - Kèthîra

Harn on World Anvil

Harnwold's Sphere became destabilized after a high tech takeover forced mass evacuation. It broke away from the Phlogistan and gates no longer reach it. It may have fallen into another plane or dimension.

Many citizens of the Free Imperia, including the Emperor are refugees from Harn, thus it is an important cultural and linguistic part of The Free Imperia.

  • World of Kèthîra
    • Continent of Lýthia
      • Harn
        • Tech takeover, gates unstable


Thought to be the center of the Planescape, Sigil is a city only entered by portals; it is adjacent to everywhere.
