In Crawford Kilian's novel The Fall of the Republic, when a gateway is found to a parallel world equivalent to 18th-century Earth, it is named Beulah, and other worlds at different points in the timestream are named for other Blake entities, such as Orc, Ahania, Los, Urthona, Thel, and Tharmas. In particular, a future world whose atmosphere has been devastated by unknown forces is called Ulro. -Wikipedia
