Although Galenos's family is never revealed, he is close with Meredy, his protege, which means a lot to him. In the course of his research, he invented the Elara Phone, a device that allows verbal communication over long distances but only common in the Celestian cities of Luishka and Imen. He also created the Craymel Express, a train that connects various cities in Celestia, as well as the Craymel Craft, a spaceship of sorts capable of bridging the gap between Celestia and Inferia. The Parasol device is another of his inventions, allowing Meredy and Keele Zeibel to immerse Greater Craymels in their Craymel Cages. Galenos was once a good friend of Shizel and her family because she sought refuge with him when they were persecuted by Birial.
