Twilit Worlds

The Twilit Worlds is the fae name for Earths 1380 and 1492 through 1496 (SUI designation), which have been the principle home of the fae and various other "magical races" since the Dragon Wars.

The name is misleading, because of them only Gloaming (Earth-1493) is actually in unending "twilight"; however, they share the property that glamour magic is not dispelled by sunrise.
