“	Viis. In the future, you might discover some unpleasant things about the world. But please remember that no matter how people may treat you...you should keep trying to do the right thing.	”
— Orion to Viis, Episode 40.

Orion was Vesta's husband and the father of Atlas. He inspired Viis to become a doctor and served as his mentor, teaching him medical skills. Following Vesta's death, he briefly took on the role of project lead before being incapacitated by Hades' poisoning.^[1] Orion refrained from commenting on Vesta's passing, viewing his relationship with her as a fellow scientist, and not husband and wife.
