The fight with Ouroboros in the Infernal Realm.
The Infernal Realm is a location in Bravely Default, the realm of Ouroboros. It appears like the void of space, with stars and a ledge in which the group fights Ouroboros. From this realm, the group also witnesses the worlds in which Ouroboros consumes. The location is unnamed in the Japanese version, with Ouroboros simply referring to it as "this world of [his]".
Etymology[]
Infernal Realm could be seen as another name for a place where demons, condemned spirits, and other evil things originate, are enthroned, or live. Different cultures have different names for these places.
