Overview
Corthis is an uninhabitable planet in the Valrindor solar system, closer to the sun than Valrindor itself. Its name comes from ancient Malverand astronomical work that also names Vireen and the distant Tyrren system.
History
Arcanis's early model of the Valrindor system includes Corthis as an inner planet closer to the sun than Valrindor. Corthis is one of the known worlds alongside Earth, Atraxis planets, Vireen, and Tyrren-IX.
In the Malverand Intergalactic Empire, Corthis is the same inner planet orbiting in the Valrindor system beside Vireen.
