Once a thriving if anonymous Nietzschean colony world and trade center, Hephaistos IV achieved notoriety as the site of the first battle of the First Systems Commonwealth Civil War. It's unclear whether the Nietzscheans actually moved or created the small black hole in Hephaistos or took advantage of an existing natural occurrence, but the wandering singularity proved to be an excellent ruse to gather an enormous battle fleet and destroy large numbers of High Guard capital ships. By the time Hephaistos IV was torn apart by the black hole's gravitational stresses in CY 9811, the planet's original population had long since evacuated. The Hephaistos Black Hole remains in the system, and was most recently the site of several experiments conducted by a Xinti research group and Andromeda Ascendant crew into quantum entanglement related phenomena.
