Expelling Angels

Expelling angels is a spell that banished angels from Heaven.

Background
This spell was unknown to most Angels. The only angel with initial knowledge of this was Metatron, the Scribe of God. Metatron convinced Castiel to perform the spell, under the notion that the spell would lock the gates of Heaven to solve the problems of the angels. Wanting to atone for his sins and wanting to restore Heaven to its former peaceful state, Castiel agreed to the plan. Naomi caught wind of the spell and its near-completion, however, she was killed by the Scribe before she could properly recruit Castiel to stop the spell from being complete.
