Iskall plopped the book onto the table. "Here it is."

The book in question was an old, dusty, leather-bound book with the title neatly set in the side and on the cover. "Fae Magic and Curses; A Guide." Mumbo read. "By... Anonymous."

"Well, let's crack on with this." Grian said, opening the book. "Okay, table of contents. Looks like an encyclopedia of Fae spells and-"

"Wait, you can read that?" Iskall interrupted Grian.

Grian frowned. "You can't?"

"Well, the cover was in English, but this page is in some kind of runic language." Mumbo said, pointing at the page.

Sure enough, when Grian looked, it wasn't in English. But somehow, he could understand it. "Huh. I don't know any other languages than English."

"It's most likely some kind of Fae runes, if Grian can read it." Iskall inferred.

"Oh. So now I can read some kind of mythical language. At least it's not something like my Iron problem." Grian said, absentmindedly flipping through the book. He wasn't much of a reader, but the contents were interesting. It spoke about different curses that Fae could inflict others with, or how humans could curse Faeries. It especially highlighted the Faerie Stroke. It was an ailment that some Fae could cast on others at will and could injure the target, and most of the time, make the target sick.

"Earth to Grian." Mumbo nudged Grian with his elbow. 

"Hm? Oh Sorry, I was just flipping through the book." Grian blinked. Standing behind Iskall was Scar, who had a notebook in his hand. " Oh, hey Scar."

"Hi Grian. Anyways, as I was saying, I might've gotten a lead on your 'condition', but I'm not entirely sure where it'll go."

"A lead?" Grian perked up.

"Yeah. Remember the dolphin glitch?" Scar asked.

"You mean the one where I was stuck flying?"

Scar nodded. "As I know, that's happened to you a couple more times since Hermitville. It hasn't happened to anyone else, as far as I know."

"And what does this have to do with Grian?" Iskall asked.

"Well, to put it simply, I don't think it was a glitch at all." Scar opened his notebook. "This 'glitch' was basically what would happen if the Dolphin's Grace spell worked on land. But you were nowhere near any Dolphins."

"So a glitch." Grian said, still not getting Scar's point.

Scar sighed. "While that is a possible reason, I don't think it holds any weight. This happened as you were about to fly into the nether portal, but when it happened, you weren't touching any blocks. Most glitches happen when a subject A, the one who gets glitched, comes into contact with Subject B, the catalyst. If you were Subject A, then Subject B would be the Air. But again, there's nothing there."

Grian still looked clueless.

"Grian, most glitches happen through contact, but when you glitched, you weren't touching anything." Iskall explained.

"Ohhhhhh." Grian nodded. "Okay, that makes sense."

"So," Scar finished, "I think you accidentally and unconsciously cast Dolphin's Grace on yourself."

Grian frowned. "But how?"

Mumbo came up with a good analogy. "Harry potter still cast magic on accident before he found out he was a wizard."

"So you're saying..." Grian finally understood.

"Yes. You've been a Faerie for a long time. And I have more evidence." Scar placed his open notebook on the table. "Earlier, I was thinking about your condition, and then I started to piece things together. For example, Fae tend to be very mischievous, and some are really good with animals. They don't see the color red as well as human, which explains Grian's redstone proficiency, and of course there's the singing. We've all had one of Grian's songs stuck in our heads at one point or another."

In the notebook was more hastily scribbled notes about Grian's personality connecting him to the Fey.

"I think Grian's always been Fae, but it took a specific stimuli to begin Grian's physical growth as one." Scar concluded. "And if we find the stimuli, well, we'll have all the information we need."
