Serenios

Serenios, the original word for "Serenity" and the home of the gods. Created by Tala-ni'alni the god of Light and Life & Khabris god of Death as an emergency home for the gods when the war with the Behemoths started to look dire. When the Elder gods banished the Behemoths it also sent them flying into the cosmos due to the amount of energy being expended. So Serenios was created for the gods much like the elemental planes were created for the Behemoths and their offspring.
