There is a door. Which is only expected, since she’s getting to the classroom where she was supposed to meet Miranda so they could play some more with Patronuses. There is a bar on the other side of the door. And that is very surprising and unexpected and, erm, what. She walks in, up to the bar itself, and notices there’s no bartender. “Erm.” A napkin: You can just ask for whatever you like and I’ll give it to you and charge appropriately currency-dependent prices for it, but your first drink’s free. She/her/hers by the way. Blink blink. “Er. Where is this place, exactly?” You’re in Milliways. This bar is connected to many different universes, and while you’re in here time at your home universe is paused. “Different universes?!” … Sadde will be engrossed in conversation with the bar for a while.
She blinks. "I'm not sure why you'd want to stop magic being a secret at all, then - it's one thing if someone needs a bit of a shock to get them to stop and think, and something else again if there are going to be problems even if they do. Or did I misunderstand something?"
"Well the main reason is that our magic is really good at, say, multiplying food or creating water, and it's actually possible to become immortal with it though only one person ever did it and they decided to go ahead and die anyway for some reason. We're also basically immune to regular non-magical disease and strife, and even without magical immortality elixir live far longer than Muggles do. So, uh, basically I just want to help everyone and uplift the species and eradicate disease and death and poverty and suffering."
The kobold takes a few seconds to consider this. "I think you're trying to do too many things at once."
"Hmm, maybe, though I'm not actually doing all of them. My current project is the networking-and-getting-influence one so that muggleborns will be treated more like humans, and then that can be expanded to nonhuman sapients. But there's precedent for both a thing that creates an elixir of immortality and a substance that cures all diseases, and the branch of magic that's used for that is uncommonly learnt and has certain other characteristics that make me confident I will be able to replicate those things when I know more."
