The "world of light" created by Maibe
Yrie is a mostly blue planet, surrounded by a vast field of metroids that are the remains of its moon. It is the personal domain of Maibe, the Goddess of Light but several of other Gods has creations or interests on it.
Yrie is mainly covered with vast, lifeless seas. There is one continent that consists of several peninsulas that together forms a shape that vaguely reminds of a spiral. The continent is covered with plant-life but also harbors a couple of creatures including the Herrim and Sun-Worms. Recently it has been inhabited by three intelligent races the Glass Titans, the Dhorem and the Blood trolls.
