An M5 class red dwarf star called Aeriant.
Of the two planets in orbit around the star, one is Orichalcos, home of the exuberant and wealthy Orichalcosan.
The second planet is an oddity, a brutally rough terrestrial world called Methuselah that appears nearly 12 billion years old, making it nearly as old as the universe itself. Due to its age and orbit, it's easy to determine that the planet must have been towed into its current trajectory at some time in the distant past.
