Takamagahara

Takamagahara is a located above the. Over twenty years ago, it became the new location for, as decided upon by Fleet Admiral Kurama.

Overview
Although it is known as a single island, in truth, Takamagahara is a collection of sky islands that are all within close proximity to one another. Fitting of an island located in the, the islands themselves are situated upon extreme air currents that make it impossible to get close to the island from all sides and all directions. Among the countless air currents that swirl around and flow upwards, encasing the sky islands, only one specific flow permits safe passage upwards and inside the air space of the islands, allowing one to enter Takamagahara. Without already being made aware of the entrance, the only way to find the current would be through an extremely powerful, or other potent means of advanced perception.

The sky islands of Takamagahara are heavily populated with all sorts of creatures, yet appear to have had no human inhabitants prior to the establishment of Marineford. While populations of wildlife required relocation, Kurama, for the most part, did not want to disturb the ecosystem on such a land; requesting that Marineford be built into the islands of Takamagahara with as minimal disturbance as possible.

Unlike most sky islands, there is an island that sits directly below where Takamagahara floats, known as Ashihara. It is here where the were built, as the specific air current one will need to access in order to enter Marineford is found within the center waters of the island. Ships enter Ashihara and follow a path of rivers that lead to the center lake where powerful air currents circle the entire area. It is there where one finds the solitary path that will allow safe passage to Takamagahara, while all others end with ships being tossed from the skies and off onto the ocean surrounding Ashihara.

Seven Realms
In comparison to the Marineford of the past, the one built upon Takamagahara is over hundreds of times larger. Takamagahara has several islands of varying levels, all within close vicinity, which allowed for Marineford to also be rebuilt as multiple successive layers that were referred to as the "Seven Realms". Each of the realms is dedicated to a specific purpose of the marines, with the highest realm being dedicated to the personal residences and offices of the Fleet Admiral and the Admirals themselves.
