Dominion is a group of Fallen Angels in the second rank.

Books of 2 Peter and Jude detail punishment of angels who committed sexual sins

“… He hath reserved in the judgment of the great day, in everlasting chains under darkness, the angels who did not keep their dignity, but left their own habitation; As Sodom and Gomorrah and the surrounding cities, which likewise indulged in sexual immorality like them and vices against nature, are given as an example, suffering the vengeance of eternal fire. Nevertheless, these also in their dreaming defile the flesh, despise dominion, and speak evil of dignities. ” Jude 1:6-8
