Coynek, the solitary star in the Coyn system, could be described as simply the average red giant, several million kilometers in diameter and many hundreds of millions more in circumference. Astrological experts predict that the star has another five hundred million years until it dies, most likely erupting into a supernova that could stretch for several light years, essentially obliterating the Coyn system. There is, however, a chance that it may form a massive black hole, potentially spelling disaster for celestial bodies as far away as the neighboring system of Torina.

Apart from its location and age, the only other distinguishing feature on the star is a small sunspot that many storytellers throughout the galaxy swear was left by a crazed Duros when he, while on a Ryll trip, plotted a course directly into the sun.
