Pay 1000 LP, then target 1 Fairy monster in your GY; add it to your hand, then, if "The Sanctuary in the Sky" is on the field or in either GY, you can add 1 of your banished "The Sanctuary in the Sky", or 1 of your banished cards that mentions it, to your hand. You can only activate 1 "The Chorus in the Sky" per turn.
