"So... what's this one, then?" "It says, "Drink this, then tell me what you've learned." "Alright, hang on. ...And here's the bucket. Okay, go ahead." "Urk! Ugh, it's got an aftertaste. Eh? Uh oh! Blaaargh!" "Well... I see you didn't barf up the spell..." "Ugh... I know she can make these potions palatable... Anything happen?" "Aye. But — truth be told, it's come so far out of left field for me I don't actually have any feelings about it!" "What?" "Have a look at the mirror." "...Oh. Wait... What?!" "Pretty much what I was thinking. No one's gonna understand, but here we are. So... what now, alicorn princess? Envy of little girls everywhere?"

So, I... I just turned into an alicorn today. I'm not used to the wings... Yeah, so, it's like... different, being an alicorn. I was thinking about maybe what I can do with the new powers, like, maybe I can use them in some awesome battle to get something I like: "Hey, now that I'm a god, you're gonna give me my books for free!"

The horn of the male narwhal, which sailors called the unicorn of the sea, is thought to have been the unicorn's horn, or alicorn, of medieval commerce. It was very widely believed that alicorn could be used to detect poisons, and when ground and added to a potion would prevent poisoning.

Tests to verify the authenticity of alicorn—most of which involved placing spiders near the horn and observing their reactions—were numerous, but apparently few detected bogus horn, for narwhal tusks, masquerading as unicorn horn, made their way into shops across Europe.
