Dantalion

Teaches art and sciences. Knows and can change the secret thoughts of all. Shows vision of the world.

Too-Faced or Two-Faced? Or looking at eachother with speculation? Or having a staring contest with your dog? It doesn't seem the be the last one... That's unfortunate.

It was only through this one that I learned of The Journey Within.

The goddess of knowledge

FUSION
To fuse two heads together to see when one has a stronger willpower.
That's why it can change the secrets thoughts of all..

A great and mighty duke, Dantalion is said to rule over thirty-six legions of lesser spirits. He is named as the seventy-first demon of the Goetia. According to the text, he knows the thoughts of all men and women and can thus declare innermost secrets of any individual. He can also use illusory power to create an image of any person from anywhere in the world. This image will be accurate in all respects, regardless of how far this person may be. When he manifests, he is said to have the body of a man holding a book in his right hand. He has many faces, however, and these faces belong to both men and women of various sorts. In addition to his other powers, he can cause love and teach all arts and sciences. According to The Goetia of Dr. Rudd, the angel Hajajel has the power to constrain him. In this text, his name is rendered Dantaylion. He also appears in the Welsh Book of Incantations. See also BOOK OF INCANTATIONS, GOETIA, RUDD.
