Oh, good point, she needs an unholy symbol. She puts up a Minor Illusion and fiddles with it thoughtfully.
"I'm damned to Hell," she says as she does so. "Everyone I respect and admire is damned to Hell. But there are many who should join us, or who should spend their lives growing in strength and confidence and power, who spend it instead fearing, denying, or trying to claw their way out of Hell, or obediently never doing the Evil they yearn to for the sake of their eternal fool. I do not call them weak or foolish, but their lives are not well-spent, compared to a world where they could go to Hell and be better off for it.
I want to make better devils using the ilani methods. Devils who have the creativity Asmodeus saw no way to build into them; devils who are competent and ruthless and interesting, whose pride is in their achievements and whose achievements make Hell glorious. I cast Vision of Hell, earlier, and people fled in terror; but there is no reason they should not be transfixed in wonder. Asmodeus is not the god of torture but of tyranny. I will build a kingdom so wealthy, so powerful, so extraordinary you would rather be a slave in it than free to wander all the rest of the Outer Planes."
