Atarinia

Atarinia is a supercontinent and the main landmass of Atar, comprising 86% of the dry surface of the planet. It was fully formed 60 million years ago by various landmasses colliding with or subducting under the Aal plate. As a result of lighter continental crust crushing the denser crust of Aal and melting after subduction, the Aal plate is subsiding below sea level.
