Oya I is a terrestrial planet in the Oya system, United Empire of Earth (UEE), and is the first planet from its sun. Small and hot, its barren landscape is riddled with deep canyons that were formed by ancient lava flows. Although all of its volcanoes appear to be extinct, the planet is still geologically active and experiences quakes, with major events estimated to occur every few million years. Its youngest volcano is roughly 100 million years old.
