The black-water ocean, a ring 8,00,000 yojana wide between the second and third continents.
Twice the width of the salt ocean, and the widest single ring in the human world. Its name means dark water, and it is described as still, deep and colourless rather than salt.
Forty-two suns and forty-two moons circle above it, more than any other ring in Aḍhāī-dvīpa.
