Abaddon was a sub brown dwarf, and is now a low-mass red dwarf around 23160 lightyears away from Sol. It was discovered in 2018, by OGLE and MOA, and was given the designation MOA-2015-BLG-337L. At the time of its discovery, it was one of the lowest mass bodies known to host satellites. In 6825 CE, the Lactean Confederacy accidentally increased Abaddon's mass to the point where it became a full-fledged star.
Before 6825 CE, Abaddon was only known by the lengthy designation of MOA-2015-BLG-337L, indicating that it had been discovered using the microlensing method in 2015 CE, a long time ago. It was one of the smallest free-floating objects ever discovered, with a mass of less than 10 jupiters, making it a sub-brown dwarf. It actually had an orbiting moon (now it is considered planet), which was quite massive compared to it, around 36.547 earth masses, making the moon a neptune-like planet. The system harboured two other planets, each around three Earths in mass, but this wasn't known for some time.
Because of how dim the primary was (Mv > +40) the system was extremely cold. The two terrestrial planets were practically frozen solid and the "gas giant" was completely thermalised, except for some kind of thin atmosphere of hydrogen and helium just above the hard surface.
Now all that changed in 6825 CE, when a giant cloud of used ships recently put out of use by the Lactean Confederacy only a few decades ago floated past the object, and at its closest approach, it was collectively only ~150 AU from the "star", and this was when the gravitational attraction of the sub brown dwarf overwhelmed the cloud of ships and it drifted towards the sub brown dwarf. The quintillions of ships present were quickly absorbed by MOA-2015-BLG-337L, which gained just enough mass to attract another, even larger cloud of unused things into it.
