Krios

While most people use them interchangeably, Archaios is not synonymous with "the Earth." Archaios is a continent; One of many across a vast planet.
  Unfortunately, until recently, very few people on Archaios knew for sure what lies beyond the vast seas. For the longest time, official documentation only referenced one other known continent known as Krios.
  Krios lies to the south beyond a vast network of islands and archipelagos. It is said to be a land of sweltering deserts and dense jungles. Legends speak of fierce invaders of bizarre snake-men and howling cannibals in addition to explorers claiming to have faced massive, serpentine dragons and giants with crocodilian heads. Since interoceanic exploration began, not one explorer has been able to verify these claims, so all of these tales should be taken with a massive grain of salt.
