**First Appearance:** #book1 An unusually hot and active red dwarf star a little over twelve light-years from Earth. The planet, Luyten-B, better known as [[Ajax]], had actually been known to Earthly astronomers for some time as the closest exoplanet orbiting within its star’s habitable zone. In 2018, a recurring music festival called Sónar had actually funded a project to transmit a radio message to Ajax, consisting of both mathematical and musical data. It is the nearest star to the space station formerly owned by Wil-Stur's grandfather, [[The Sanctum of Righteous Fury]], now owned and occupied by Wil-Stur.
