This is the only location on the ocean's floor that light reaches. That is becasue of the roots of the Sun Tree Eve (陽樹イブ Yōju Ibu) reaches from the top of the Red Line and to the ocean floor. There are many theories for the reason, but the tree absorbs the light from the surface and carries it all the way to the roots.
