Legracia

Home of the Humans

• Gravity: 1.05 x Earth
• Diameter: 1 x Earth
• Atmosphere: Oxygen-rich, 1.5 times denser than Earth.
• Day Length: 28 hours
• Moons: 1.
• Binary: No.
• Environment: Large continents framing large, deep oceans. Legracia has a modest tropical zone that eases to permanent polar caps.
• Orbit: Nearly circular.
• Tilt: Moderate. Seasons are marked and definite.
• Sun: Binary yellow dwarf a little larger than the Sun of the Earth.

Notes: 

Legracia is one of the Founding Worlds, or Core Worlds of the Cooperative. It also frequently hosts Council gatherings to vote on Cooperative issues. It is very similar to Terra, but much wilder with more unmolested forests. The population tends to congregate around and in lakes and swamps,which are overwhelmingly numerous on that planet. Various habitats are used, from tree-houses closer to the shore to large living piers and floating islands on which homes are grown. While the exterior of the homes compliment the nature within which they are placed, the interiors are much more modern.

Telestra

Endard’s Sister

• Gravity: 0.95 x Earth
• Diameter: 1 x Earth
• Atmosphere: Oxygen-rich, 0.80 times denser than Earth.
• Day Length: 20 hours
• Moons: 5 small asteroid moons. Several rings, similar to Saturn.
• Binary: Yes. Endard is her sister.
• Environment: A world similar to Venus. Planet Builders are working to make Telestra habitable.
• Orbit: Mildly circular.
• Tilt: Moderate..
• Sun: Solitary yellow dwarf a little larger and brighter than the Sun of the Earth.

Notes: 

Telestra has all the ingredients to become a habitable world. Except there is a runaway greenhouse effect that is keeping it unlivable. The Trolls are working to solve that problem, however, and give the Selkies a second world.

Toros

Home of the Keratians

• Gravity: 5.10 x Earth
• Diameter: 2.35 x Earth
• Atmosphere: Oxygen-rich, 2.85 times denser than Earth.
• Day Length: 31 hours
• Moons: 1 moon size of Mars.
• Binary: No.
• Environment: Large continents framing large, deep oceans. Toros has an extended, mild temperate zone that eases to permanent polar caps.
• Orbit: Nearly circular.
• Tilt: Moderate. Seasons are mild.
• Sun: Red dwarf, a little dimmer than Earth’s Sun.

Notes: 

Toros is on the heavy side of the Cooperative worlds, weighing in over five times the gravity of Earth. Even so, there is little stunting of the native forest vegetation. Their trees within whose trunks the Keratians carve out their homes are tall, nearly conical in shape. The toughness of the Keratian is a direct result of the extreme nature of their home.

Dherring

Home of the Ordan

• Gravity: 2 x Earth
• Diameter: 1.6 x Earth
• Atmosphere: Oxygen-rich, 3 times denser than Earth.
• Day Length: 27 hours
• Moons: 3. Two are Mercury sized, one is more like Ceres.
• Binary: No
• Environment: Largely rocky landmasses and deep oceans. Only patches of forests. Dherring has a large tropical zone that eases to stable polar caps.
• Orbit: Nearly circular.
• Tilt: Mild. Seasons tend to be mild and stable.
• Sun: Solitary yellow dwarf similar to the sun of the Earth.

Notes: 

Dherring is a periodic target of a pulsar a few light-years distant. As the pulsar wobbles, its beam of radiation washes over the planet, overwhelming the magnetosphere and stripping most life from the surface. The greater portion of life is subterranean and oceanic. The Ordan was the former.

The Ordan were finally able to rise above the caves as their technology improved until in contemporary times they occupy tall cities that dot the landscape. The pulsar now creates a pretty light-show on their shielding every few decades. Their prowess in technology that stemmed from their habitat innovation translated well into the needs of the Cooperative. Their first city is Rosteran, and this city is where much of their manufacturing for the Cooperative takes place. Their manufacturing capabilities also exist in orbit as well, exploiting microgravity.

Mor’ite

Home of the Leif

• Gravity: 1.25 x Earth
• Diameter: 1.1 x Earth
• Atmosphere: Oxygen-rich, 2.5 times denser than Earth.
• Day Length: 31 hours
• Moons: 2 moons size of Ceres.
• Binary: Yes. Mor’ite orbits a hot brown dwarf.
• Environment: Large continents framing large, deep oceans. Mor’ite has a modest tropical zone that eases to seasonal polar caps.
• Orbit: Nearly circular.
• Tilt: Moderate. Seasons are mild.
• Sun: Binary white dwarf. Its partner is the brown dwarf that Mor’ite orbits.

Notes: 

Mor’ite is an ancient world in a system lit by a white dwarf. It is kept warm by the hot brown dwarf it closely orbits. Its forests are largely fungal-based. The brightest part of its day is closer to Terra’s golden hour. Its system contains some of the richest asteroid mines in the Cooperative.
