The Grendl Stars are a constellation of stars located on the far Eastern Fringe of the Milky Way Galaxy that were once known as the "Wings of Sanguinius." They are now known to harbour the hyper-violent xenos race known as the Barghesi. According to Imperial records, the Space Marines of the Iron Lords Chapter proved instrumental in confining the Barghesi to the Grendl Stars, and also in preventing the destructive biological potential of the species from being harvested by the Tyranids' Hive Fleet Kraken.
