The Gnawstar Cluster is a region of the galactic core located like a splinter near the northernmost Kindreds of the Urani-Surtr Regulates of the Leagues of Votann.
These worlds are haunted by an infestation of Tyranids that exhibit strange, almost nesting behaviour patterns unusual for their species, and are ever-hungry to claim new worlds to infest.
