The Domed Paradise
Dunia is the established name for the world. Originally an abyssian term to refer to the world as opposed to other islands and islets, it has become the accepted term even in everyday speech.
Dunia is also known as simply "the world", the Dome or Geislheim. Geislheim is an ancient term, from before recorded history. Using linguistic studies, one can derive that it originally meant something like "The Light Realm", "The World of Light" or "Light's Home" and was contrasted by Grímarheim, a term that appeared in feudal times and referred to the Shadow Realm.
