Magrön

Unlike most other worlds in TWoD, Magrön is not a planet. It is made up of three so-called "continents", Seibul, Haile, and Lagrën; planet-sized indents in the Blackrock layer covering the inside wall of the shell of the universe, Onu.

In essence, then, Magrön can be described as a series of three grand valleys at the edge of the universe. However, Magrön is not only made up of the surface, and in fact encompasses an even comparatively colossal underground network of caves, caverns, mines, buildings, and other underground areas called The Abysmal Depths, which is considered as an unofficial but still majorly significant World of its own.
