Chalybeas is a home planet for Citrakayah. Not much of this planet is known right now. It's home to the alien Fasttrack.
In Brett 10, Brett and his friends ventured to Chalybeas to obtain a Citrakayah DNA sample after Darkanoss stole the original from Brett's Omnitrix. In Brett 10, Chalybeas was a lush, blue world with many plants and dangerous creatures called Carykatians that are the predators of the Citrakayah.
