When the human body dies, the brain is flooded with N,N-Dimethyltryptamine, which controls states of consciousness. It is often said that the entire life of an individual may flash before their eyes during this short transition. Xane was a mortal in passing.
He is watching himself before a star of critical mass, ejecting the rest of its fuel as it becomes a black hole. So close that he sees the gravity of his own reflection, red-shifting while it moves across the event horizon, Xane is the starlight entering the black hole. He faces his judgment, and all the different outcomes of his life experiences replay as he is cast into the void.
The information of his existence is forced through a singularity. Xane's memories are strings of the aether. His consciousness interacts with other dream-membranes, forcing him to experience death as other transient human entities. He becomes lucid simultaneously and is jarred from this 6th dimensional state of existing in multiple shape-shifting universes, to a 7th dimensional state in which he is all of those universes. Enlightened, he realizes a pathway to this objective Omniverse of Nirvana, but it is clouded by his self-judgment and cognitive dissonance.
On this plane Xane comes in direct physical opposition with his doppelgänger. In learning his association with this enemy, he transcends through death, spiraling once more, rising into the 8th dimension that hosts all possible beginnings and endings to every universal state below his phase space.
In his Supreme form he sees mirror versions of all the universes that he is, surrounding him. His perspective of existence is embrightened once more to reveal him as a Colabi-Yau manifold. With all his energy he paints these joined octeracts. Enveloped in Brahman, staring into this painting, he is inundated by the divinity of his infinitude. Alas, his love for beauty is all-consuming. This great 10th dimensional point Is, and it is the same singularity that he Was and Is on a lower dimension at the end of his life. So Xane reincarnates as a mayfly, living in one day only to have sex and die, facing the black hole again.
