The Eleuthean Realm was the most advanced and mightiest of all the states that existed in Arbrèa, a planet lost in the constellation of Libra. For reasons unknown, the planet was colonized by humans in the distant past, and they thrived there for many centuries. Eleuthèa represented the culmination of the human society and culture in that distant world, until everything and everyone were toppled and crushed in the Dhaula Varlauve, an enormous catastrophic event that put an end to the human civilization in Aerglè.
Shortly before that, Riam Tanyersac, an Eleuthean researcher who foresaw the disaster, managed to create a new world by means of magic, the
Ybrearmèlleon, where all the survivors of the Dhaula Varlauve now prosper.
