Elizabeth
Elizabeth smiled. "With age comes wisdom, and I've learned people are far more loyal if they actually like you. And the relationship is a lot healthier too. You don't get betrayed at the last moment by your lieutenant and sealed..." She frowned a bit, sitting down on her throne across from Hannah. She placed her fingers together in an arch and looked at her thoughtfully. "Why don't you tell me all about your magic, Hannah. You seem to be a powerful spellcaster to me."
Hannah"Huh. I guess that's a better way to look at things." Hannah's voice trailed off as she took in Elizabeth's discomfort. Politely, she chose not to comment on it. Not when the greater demon had other questions on her mind anyway. "I guess I might as well. Hopefully it's compatible enough you can teach me a thing or two. You see, where I come from there is no magic. Not normally, anyway. The world is just cold, mechanistic physical laws. Minds are just emergent phenomenon arising from the systems of the human body; souls aren't real."
The sorceress folded her hands on top of the table as well, her face growing serious as her lecture went on. "But there are other worlds, and their Laws are different. I am connected to Hell by blood..."
She went on to explain, then, the intricacies of infernal Law and how it compared to a soulless world of science. She spoke of the chaotic landscapes of the Nine Layers, of the black citadels of the demonic nobility which imposed order on worlds who burned with the anguish of their own sins. Hannah spoke of the Denial of Obligation, the process by which the Laws of Hell impose themselves on other realities. They created a spiritual weight and karma on the actions of those affected by them, allowing for Hell's damnation to draw them in like a magnet for their deeds. Magic was Hell's instrument, a means of spreading its Laws upon the physical fabric of reality while corrupting the newfound soul of the sorcerer with the temptation to abuse it.
Hannah was a prodigy, not that she described herself in such terms, and could do much with it. She was a conduit for blasphemous Law, imposing it on the world to reshape it to her selfish will. The transmutation of matter, the alteration of properties such as distance and density, the violation of the mind, the conjuration of Hell's burning essence and its inhabitants, and masterful illusions. She could also, she noted with a smile, see through pretty much any lie presented to her - deception was the instrument of infernal invasion.
"I even managed to hide what I was from your- um, my coworkers when I first got here. Oh, and I made these!"
Hannah sounded actually excited as she whispered for her purse of holding to return to her, the bag containing all that she brought with her. Including the Infinite Codex, her self-updating and self-indexing book of everything.
