In the Christian hierarchy of Angels, Dominions are part of the second sphere and are said to watch over nations and regulate the duties of lesser angels.
In Moses Maimonides' hierarchy of angels according to Jewish lore, they are Hashmallim, the fourth rank of angels, and are mentioned briefly in the Hebrew version of the Book of Ezekiel. It is only with extreme rarity that the angelic lords make themselves physically known to humans. They are also the angels who preside over nations.
The Dominions are believed to look like divinely beautiful humans with a pair of feathered wings, much like the common representation of angels, but they may be distinguished from other groups by wielding orbs of light fastened to the heads of their scepters or on the pommel of their swords.
