A terrestrial planet in the Nugi System with an extremely slow axial rotation. Days and nights here can last as long as an Earth-week (depending on the season). Forests of giant fungal organisms dominate much of the surface. The flesh of these huge mushroom trees dry out during the long, hot days, becoming tough and woody. Building upon this hardened material is what allows them to grow so tall. One large settlement has been established on the surface, known as Chanterelle. Arion provides many food exports to different planets within the Terran Empire, aswell as valuable biology research.
