Nereis is the fourth planet in the Etheria System. It is a large terrestrial planet, however it is considerably different than Earth or Etheria. Roughly 95% of its surface is covered by water, and it has a quite thick atmosphere, whose greenhouse effect is the reason the planet hasn't frozen over. Additionally, any visitors from Earth or Etheria would likely quickly suffer from mild nitrogen narcosis due to the increased pressure.
