What the fuck actually IS Stolas' job, anyway? We never see him do anything at his mansion other than lounge around and think about imp dick, he claims he needs the grimoire to do his job, but he only gets it once a month on the full moon, are those days of the month just suddenly really productive until he makes Blitzo fuck him? There's not a single hint he taught Octavia, his heir, a damn thing about magic or taking over his title, and the blue peacock guy implies he owns the 26 legions he's stated to have in the Ars Goetia.
What are those legions doing? Are they demons? Owls? Imps? What does hell have legions of soldiers for?
