Astral Saga: Stars of Strife
The Parlanz have a particularly strong affinity for magic, which was noted by a Crownbearer that was in hiding on their home world. They were instructed in the ways of Eldritch Sorcery, becoming the most magically adept of the Mortal races. While they did not develop any interstellar vessels on their own, they were aware of the goings-on throughout the galaxy, as they observed through astral channels.
When the Crownbearer’s interaction with them drew the attention of the Traitor Crown, the Parlanz enacted a powerful ritual to transport their entire planet to another location, escaping the Traitor Crown. This also placed them in the territories of the Sanctarchy of Balaat, to which they swore their allegiance.
