The Lathrym (pronounced Lath-rim) is one of two over-realms in Universe X, second in size only to Ersis. While Ersis holds the Seeds and Humanity, the Lathrym holds the Arkn, Dekn, and everything else, and encompasses the entire universe beyond Ersis.


The Lathrym is an empty white space composed of red tears that lead to sub-realms. If one were to look into the Lathrym from outside of Ersis and the Seeds, it would look like a blank, white sky with distant red stars.

The Lathrym possesses a breathable source of air known as Aeri. Arkn and Dekn have evolved to breathe Aeri. Humans, despite not being native to the Lathrym, are also capable of breathing it.
