Thistlings

The Thistlings are the mortal enemies of the Thister-Arcs and according to the stories told by the exiles at Anoomenon, they have driven the Thister-Arcs to the brink of exinction.

No human has ever seen one of the Thistlings as they have never come to Earth. Nothing is known of their culture, appearance or habits, beyond the stories told by the Thister-Arcs and without corroboration this can be considered as no better than hearsay evidence.
