Grallion was the habitat where Vo Spader lived. It was an enormous farming habitat. Later in the book, Mogorran crashed into Grallion because Saint Dane poisoned everyone on Mogorran including Benn Spader (the first generation traveler from Cloral) so no one was controlling it. In the Soldiers of Halla, Ravinia attacked Grallion because there where exiles on Grallion. Grallion also had a tavern-like place called Grolo's where they serve drinks called sniggers.
