Primary star — Asterra
The Asterra star system is dynamically stable and long-settled. Most permanent infrastructure predates the loss of Ytharia and was designed for extended autonomous operation.
Companion star — Carmyn
Carmyn is the red companion star of the Asterra binary system, orbiting at a wide separation that renders it a naked-eye fixture in Ytharia's night sky — a dim but constant red point, distinct from the stars of the broader field. Its slow drift across centuries of recorded observation made it a cultural and navigational reference point long before its stellar nature was understood.
