The Realm of Drehmal¶
A mural depicting the bodies of the realm. From left to right: Lo'Dahr, Loruhn, the Disc, Lorahn, Lo'Veruhkt, and the Torahn.
Broadly, the Realm of Drehmal refers to the planetary system of celestial bodies contained within the Veil, roughly equivalent to Earth's solar system.
This includes the disc upon which Drehmal and the (not in-game) continents of Xivrhynt are found, the Torahn, and the four moons: Lorahn, Loruhn, Lo'Dahr, and Lo'Veruhkt.
The realm appears to operate in a roughly geocentric manner—the moons and sun all orbit or are positioned around Drehmal, with the exception of Lo'Dahr, which is also stationary relative to the disc.
