Metatron is in charge of the Akashic field/etheric plane. 🙂 He is located in the zero point Field and sometimes he meets humans here.
He will never show his face.
Most of these beings are called Cherubim in human terms but actually I believe they are zetas.
So much of my awakening had zeta influences. In fact they selectively heal. They are masters of energies and even help to eradicate karma.
They will teach you white tantra if they think it will help you.
hope this helps!
