Sea beyond

The sea beyond (海以遠) was a neutral afterlife spoken of and believed in by most pirates and bounty hunters, as well as other seafaring occupations. All those who had lived and/or died at sea are brought here after their death, regardless of their morality. It is said to be an endless ocean, expanding in all directions with only small islands and boats here and there. Devil Fruit users are capable of moving around freely even within the water, as with their death such powers have been stripped from them. An individual supposedly arrives near friends, family, and other loved ones who have passed on, reuniting with them. There is no conflict in the sea beyond, and it is described as being both an "eternal voyage" and "eternal festival" by various individuals; a land of bliss for the seafaring soul.

Those exposed to large amounts psychodelia coral for extended periods of time are said to occasionally experience hallucinations in which they visit the sea beyond, and can even converse with souls that reside their. Pounce D. Luk's left eye, after being impaled with the substance, is remarked as now being the same color as the sea beyond.
