Baraqiel, The Living Vessel
https://www.angelarium.net/grigori/#/baraqiel-angel-of-lightning/
The rituals Baraqiel performed were an object of fascination for both
men and Angels alike. He brought to them the gift of tamed lightning.
Despite the widespread appreciation for the fruits of this work, few
volunteered to assist. Baraqiel was known not only for the power he
commanded, but also his lack of respect for it. His fall was the first
to prove that Watchers were not complete in their wisdom or their
immortality.
