Alinos is one of two planets in the Alimbic Cluster, and the homeworld of the Alimbics themselves. The planet has become geologically unstable since the destruction of the planet's core, with many volcanic caves and molten lava flows. Most of the areas visited here are Alimbic ruins, some with still-functioning machinery that taps into Alinos's active volcanic vents to collect geothermal energy. The planet is also home to the Alimbic Cannon, a massive energy weapon that, when activated by the eight Octoliths, can open a spatial rift to reveal the Oubliette, the prison of the ancient monster Gorea.
