The center of the world is the great continent known as Ixalan, which has given its name to the plane as a whole. A tropical land covered in lush rain forest, soaring mountains, lofty plains, and winding rivers, Ixalan is shaped like a large crescent enfolding a vast inner sea. Its history has been shaped by the interaction between the Sun Empire and the River Heralds. Both peoples lived in balance while the Sun Empire maintained its stewardship of the Immortal Sun. But that balance was upset when the emperor abused the artifact’s power. Now the Sun Empire has been pushed to the coastal lands of Ixalan, while the River Heralds dominate the interior.
