Daisuke Watanabe, the lead scenario writer for Final Fantasy XIII-2, has explained Valhalla as thus: "Valhalla exists on a different reality plane, one that lies between the real world and nothingness. Time doesn't flow in Valhalla because it is a timeless, lifeless place. With Etro fading from the real world, Valhalla is her only refuge: it is a 'middle world' where she waits until she dissolves completely".
