Fictional info (?)
Suggested nameGyuan
Planet typeCold planet
When viewed from Einyangr, Gyuan can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. This planet is named after the deity Gyuan, the creator of war.

It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.

The surface of this planet is crowded with passive minded poisonous plants called the "Wogo". They survive in the jungle by eating smaller pray if they can. Most Wogo are not related to the Hyao Kwei-g, have 3 arms and vary in size from 70 to 100 cm. The Wogo are known to live at temperatures from -20 to 20°C and even drought which is common on Gyuan.
