Location from Overlord by Kugane Maruyama
A 4-square-kilometer jungle with an artificial sun — Aura and Mare's domain, the largest floor in Nazarick, containing an Amphitheater and the Gigantic Tree.
Floor 6 is Nazarick's largest floor — a complete jungle ecosystem with its own weather, artificial sun, and native creatures. Aura tames the beasts here while Mare manages the flora. The Amphitheater serves as a gladiatorial arena where Ainz has tested combat scenarios. It is simultaneously a nature preserve and a killing field, depending on who's visiting.
A vast underground jungle illuminated by an artificial sun — 4 square kilometers of forest ecosystem inside a tomb. The Gigantic Tree serves as Aura and Mare's residence. An Amphitheater provides a combat arena. The contrast between the natural beauty and its underground location is surreal.
Also known as: 6th Floor, Jungle Floor, Aura's Domain
