Valcea was one of the worlds in the Enclave, and was the home planet of the Glass Men (PROSE: The Blue Angel) and the Valceans, Valcean beasts, and Valcean Steeds. (PROSE: Enter Wildthyme)

Twenty-four Earth hours was equivalent to two and a half Valcean days. (PROSE: Enter Wildthyme)

30,000 years after the Eighth Doctor's visit to Valcea, the planet had become home to a series of segregated societies that rarely interacted. The New Gods ruled over the remains of the City of Glass.

Iris Wildthyme, Panda, Barbra, and Simon visited Valcea during their search for Anthony Marvelle. After a night at The Winged God, the bartender tricked Barbra into accepting a batch of eggs, one of which was a bomb. Iris and her friends then drove to the City of Glass and faced the New Gods. The bomb inside Barbra was then removed by Jenny Winterleaf and Euphemia, and the bomb then shattered the City of Glass. (PROSE: Enter Wildthyme)
