I’ll be covering the angel mentioned in the GKoS, Iachadiel; His name is on the 5th pentacle of the Moon, with the description “Its Angel Iachadiel serveth unto destruction and loss, as well as unto the destruction of enemies. Thou mayest also call upon him by Abdon and Dalé against all Phantoms of the night, and to summon the souls of the departed from Hades“.

Iachadiel is Lunar (19° in Cancer- Dilettante) and favors, as His description states, destruction and loss; destroying enemies and undoing events & situations is His “thing”.
He can be approached for general Lunar affairs, but is reluctant in general about these. His appearance is that of a generic angel dressed in white robe etc. Aside from the aforementioned, He can aid one in focusing one’s mind and mentality, and improve self confidence and mental alertness.
