Argos A and B
Only four worlds orbit Argos A, a K5 star that has already seen the passage of more than 12 billion years. Two of these worlds are gas giants large enough to influence the orbit of their parent star. Another is a lifeless rock without interest to anyone. Proteasa, the fourth planet, lies just beyond the lifebearing orbit of Argos A and has developed sulfur-based organisms that include both animal and vegetable life. However, scientists haven’t confirmed the presence of sentient life on Proteasa.
The pleasant warmth of Argos B bathes its young planets; however, none of these worlds has developed life. Given time, either Marybelle (G2/R1/A3/P3/H2) or Hartrest (G2/R1/A3/ P4/H3), two planets that lie within Argos B’s habitable ring, may one day produce their own biosphere. The arrival of sentients, though, has changed the planets’ destinies; these colonists have their own plans for both worlds. Native life won’t be given enough time to develop on its own.
