Grachiel

Grachiel is a supposed demon with no recognizable origin from the Standard Set. Its sigil bears a very rough resemblance to the symbol for garnet from the Dictionary of Occult, Hermetic and Alchemical Sigils. The Standard Set also titles Hagonel as "Lord Under Grachiel", and while Hagonel does have origins from the Heptarchia Mystica, none of its servants are related.
