Seraph (John Dee, Jenny Everywhere: Round One)
From Jenny Everywhere Wiki
A "blackly scintillating" seraph was one of six angels which were summoned by Jenny Everywhere in one universe by speaking Enochian in order to prevent John Dee from escaping. This particular seraph notably threw Ed Kelley back into the room after he'd fallen out the window, allowing him to continue harassing Dee. (PROSE: John Dee, Jenny Everywhere: Round One)
