There are over 1,000 planets in The Realm of Aethon, sages dispute the exact number. Planets are biologically diverse, many species only exist on a single planet, while other life forms are common throughout the solar system. Planets also have a variety of magical properties. Magic functions normally on most planets, but some enhance or diminish certain types of magic.

General Characteristics of Planets

  • The largest planets have a surface area of about 280,000 sq. km (108,109 sq. miles). They are about 300 kilometers (186 miles) in diameter. They have a similar surface area to the state of Nevada.
  • The smallest Planets have a surface area of about 800 sq. km (309 sq. miles), and are about 16 kilometers (10 miles) in diameter. They have a similar surface area to New York City, Dallas, or other large cities.
  • All planets have the same day length, 24 hours.
  • They all have different orbital periods (years) depending on their orbital speed and distance from the star.
  • Climate is determined by the distance from the star, and the make-up of each planets’ individual atmosphere. While the entire solar system shares an atmosphere, the air between planets (called the Nether) tends to be very dry, and does not conduct much weather. Instead, the amount of moisture in each planets’ atmosphere is held there by gravity, giving each planet its own weather and clouds.
  • All planets have the same gravity, which is identical to Earth’s gravity. The pull of gravity does not extend nearly as high above the surface of the planet, however, making escaping it much easier (see Interplanetary Travel). The extent of gravity depends on the size of the planet.
  • The planets are relatively close together. It usually takes a day or less to travel to the nearest planet by airship, if it’s nearby in its orbit. It take several weeks to cross the solar system.

Notable Planets

Here are some of the most significant planets, listed in order from closest to farthest from Aethon. Planets that are next to each other on the list are not necessarily next to each other in orbit. This is only a small sampling of planets.

  • Murugan is a small, hot, highly volcanic planet. Murugan is the home world of the Tiefling, and demons are also common.
  • Crisium is a small desert world. It is the home to the Eladrin.
  • Maria is a large, warm world covered completely in water. Beneath the surface, vast Sahaugin and Merfolk kingdoms battle for supremacy, and enormous sea monsters cruise the depths.
  • Tarnar is a world of vast grasslands and semi-arid planes, with occasional groves of trees. A relatively small world, it is home to the Halflings.
  • Varaha is a large world that harbors an unusual diversity of climates. Snow-capped peaks, blistering deserts, and steamy jungles can all be found. Varaha is widely believed to be where dragons originated, because there are still many there (as well as on other planets, which they can fly to freely). It’s also home of the Dragonborn.
  • Kurma is small forest world which is home to the Gnomes. Many exotic plant and animal species also thrive here.
  • Trucidor a world of temperate savannahs, home to the Gnolls.
  • Sylvania is a temperate forest world. It is the home of the Elves.
  • Gaia is the home world of the Humans. It is a diverse, somewhat warm, temperate planet with seas and many different topographical features. There are mountains, semi-arid steppes, and forests, but the majority of the planet is covered with lush grasslands. Several human empires compete for power over Gaia.
  • Gruumitar is a large world filled with craggy peaks, inhospitable forests, and stinking bogs. It is the home world of the Orcs.
  • Kigahara is strange and foreboding world, widely believed to be cursed. While its dense forests are always filled with fog, it never seems to rain. Visitors notice colors seem much duller here. There are no known intelligent species.
  • Regolith is a cold, rocky world, filled with dense mountain ranges and glaciers. It is one of the largest planets. It is the home of the Dwarves. Giants are also native to Regolith. There are countless mines carved into its great peaks, where the Dwarves mine all manner of metals and minerals.
  • Lectaris is a cold, unforgiving world with no native intelligent life. Many kingdoms throughout the solar system have taken to using Lectaris as a prison colony. The cruel souls abandoned there have formed their own brutal kingdom.
  • Naruna is a cold world, far from Aethon’s warmth. It is covered with half-frozen seas, glaciers, and permafrost tundra. It is the home world of the Goliath.

Rogue Worlds

Characteristics of Rogue Worlds

  • Some rogue worlds have elliptical orbits which cause dramatic climate changes unlike any other planet. Elliptical orbits also make collisions with other planets possible, there have been several notable collisions in the past. While these collisions are usually able to be predicted by calculating orbital paths, some rogue worlds follow orbits that seem entirely illogical.
  • Some rogue worlds are deeply warped by powerful magic. These extreme worlds do not behave like normal planets. Some are invisible unless one stands on the surface, others phase in and out of detection, while still others appear here from distant realms, only to disappear. These types of rogue worlds are thought to be the home worlds of extreme monsters that are out of place in the known planets.

Notable Rogue Worlds

  • Valhent is moon that appears for a short time orbiting various planets. It is believed to be a myth.
  • Zirkle is the home world of the goblinoid races. It has an elliptical orbit. Its perihelion is near the orbit of Tarnar, while its aphelion is near the orbit of Regolith.
  • Hallendren is a planet whose orbit is on the distant, outer reaches of Perihelion. The capitol city is Teod.
