Huo Xing

Huo Xing, previously called Antares, is the brightest star in Scorpius. It's the capital system of the Kerberos Alliance and the central star of the Xin Xiu Sector.   The binary system consists of a red supergiant and a blue main-sequence star. Three planets are known to orbit the primary, all now swallowed by the bloated star, but that didn't stop the locals from settling the scorched worlds.  

Name

After its settlement, the system was renamed to Huo Xing (火星, Huǒxīng, "fiery star"), a name previously also given to Mars, but also an epithet given to the star during the SHang ddynasty.   Unlike Sol's red planet however, the star's byname is commonly written as two words in the Latin transcirption. The local pronunciation approximates that of the original Mandarin.   There were two reason for renaming it. The first was the primary's appearance and the discovery of the three planets in its outer atmosphere reinforced that. The second is the association of the Hellhounds with fire.   Huo Xing is the home system of the species, and its planets the reason the Hellhounds got their specific adaptations allowing them to survive, if only for a limited time, on the scorched surface of the outer planet.

I like that it was previously called Antares. I'd like to know more about why the name was changed. :D

A couple well-known stars got renamed upon settlement. I'll get into the various reasons the locals had eventually. In this case fire is a bit of a theme with the folks living there (this is central Hellhound territory, after all).
