The Wyewoman ea (Portugalish: Rio Amazonas; Spanish: Río Amazonas; English: Amazon River) is the biggest ea on Earth, flowing through South Nightland for 6,387km. Its headwaters are in the Highcombs, and its mouth is on the shore of the Even Highsea.

Mostly the Amazon flows through Rudwood, though its upper waters are in Peru, Bolivarsland and Goldhern. The greatest stead on the ea is Mother of God. Other steads are Palmdwelling, Holyirene, and Watersunderedfolk

So much freshwater flows into the sea at the mouth of the Wyewoman, that the sea is not salty and can be drunk.
