 (Paraphrased from "The World of Ice and Fire)"

To the south of Essos is the continent of Sothoryos (mistakenly spelled Sothoros in early novels).Sothoryos is the third continent of the known world, and is vast, plague-ridden, covered in jungles, and largely unexplored.It is reported to be as large as Essos and described as a "land without end" by Jaenara Belaerys, a Valyrian dragonlord from before the Doom of Valyria.
