Planet Icriss

Planet Icriss (惑星イクリス) is the fourth planet the students of Caird High School visited.

Principles
It is known to be orbiting a red dwarf star and is tidally locked, meaning that one side of the planet always faces the sun, causing that side to be incredibly hot and uninhabitable, and the side not facing the sun to be incredibly cold and also uninhabitable. However, there is a temperate zone in the middle where life is able to flourish.

Icriss is noted for its carnivorous plants and barren landscape.

Trivia

 * Icriss is an anagram for the word "Crisis."
