There is a place, a place where fantasy crashes head-on into reality, where pure creation is met with utmost destruction, where chaos is orderly, and where the Mind becomes Matter. This place is the inner essence of a homunculus. Today, along with two other brave human souls, I ventured inside my own essence, and found... I don't even know how to describe it. This place simply is.
— Exerpt from the Journal of 2.0
The Inner World of 2.0 the homunculus exists within his own essence, floating around as a sort of 'pocket universe'. To enter, one must utilize a special purple Teleportation Stone, which is linked to a Central Teleportation Stone that 2.0 placed inside his essence. The Inner World is much like a dream world, where mere thought is enough to reshape reality. There are no outposts here, only explorable areas; all of which are floating islands, connected by a mysterious boat that sails the vast emptiness between. Each area discovered so far is representitive of some memory or emotion, with many of the locations (such as the Jade Quarry island, or the faux Orphans Of Kukai guild hall) being based off of physical locations that are of some importance to 2.0.
