With only Angelica and himself in the library, Charlemagne heard questions he didn't expect to be presented with at this point in a 1,000+ year-long life. He supposed however, that if he was going to actually marry the Holy Princess, she deserved to know the truth eventually. He'd be better off telling her that sort of thing beforehand. As such, Charlemagne pulled two chairs away from a nearby table, placing them beside each other, angled slightly inward. He sat in one, and patted the other briefly. "Ah... right," he said, seeming to almost dread the fact that this topic had come up. Life in that other world was so very long ago, yet still so precious a memory. Things were simpler then. Yes, people like him were living a dream in a magical world... but there was so much more to it than that.
"We're not clairvoyant. Well..." Charlemagne paused. Toward the end of his date with Angelica, he wondered if he was developing some form of Clairvoyance. Alas, that had nothing to do with the current topic. "I should say no form of magical foreknowledge is going into the stuff we say. I guess, if you're sure about the whole marriage thing, there's something I should tell you."
Charlemagne had never intended to keep his previous life a secret. On the other hand, he hadn't a clue how to even broach the topic. Now was as good a time as any, he thought. "So, Angie. Imagine... life in this world suddenly ended for you. Ugh, wait. That sounds morbid, doesn't it? I mean... imagine you wake up tomorrow, and nothing's the same. Close your eyes. You've been born all over again, all your memories intact, but you're a completely new person. You're born to new parents in a world with no magic. Because magic and magecraft never existed, people who wanted to start fires used methods like what I showed you earlier... but eventually, humans found better ways to do everything. Instead of doing so much, someone creates a little thing that fits in your pocket, which could make a little fire you could use to ignite something else. The world has no rideable flying creatures, so a couple of guys threw together a bunch of wood and fibers with wings, all to be more like birds. Even that evolves beyond those two guys, with future people making even bigger versions of it out of metal that could carry hundreds of people at a time. Instead of mana, devices of all sorts use the energy of burning coals, then fuels, then motion, then lightning that someone learned how to harness without any magic at all!" Once more, Charlemagne had started a tangent. This one, however, was no rant. He was recalling human innovation from his original, nonmagical world, and he was doing so with the twinkle of fondness in his eye. "Just think. Can you imagine that? Can you see yourself falling asleep right now, and waking up to something extraordinary like that?"
