Noachos, a young mars-like planet with a thick atmosphere and surface water
Arean Type planet. These worlds have substantial atmosphere, fueled by heavy volcanism and impact events. Surface water is present, often to a great degree, and usually support primitive microbial life forms, or at the very least pre-biotic forms. Depending on a variety of conditions, these worlds may develop into Gaian or Cytherean type worlds. Most typically, however, they turn into standard Arean Type worlds. Plate tectonics, if present, are very rudimentary.
