I'm having some issues going into this next post.  I got two conflicts - one, I'm still unsure of the nature of her hellish powers or how powerful to make her.  I don't want her overpowered, of course, but she's the friggin empress of hell, possibly a fallen angel, she's gotta be powerful.

Two, I'm debating how she'd go about this conversation.  Part of me wants to make her all business, regarding everything like it's beneath her and just going about everything as efficiently as possible.  But another part of me wants her to have fun with everything.  She's so completely assured of her control of the situation, that she might as well enjoy it.  I worry that's going to act against her personality.  But the former makes for a less interesting interaction.

Perhaps, for her powers, I really should just make something up.  While my concepts for the empress are inspired by Christian theology, I really ought to just create an entire theological story mostly from scratch.  
Let me know if you have any ideas.
