Thrones

The Thrones are one of the nine choirs of Angels. They are the "first order in the third sphere (...). They are the companion angels of the planets. At this time in your history it is important for you to be aware of the particular throne, the Earth Angel, who is guardian of your world." (From Ask Your Angels).

Some esoteric traditions refer to the 'Earth Angel' as Lady Gaia, an ascended master.
