“Argh. Now that we have that out of the way…” Twilight slapped the pointer against the back wall, changing the image to what was on the chalkboard before. “We can discuss the remaining two summits: wings and the ethereal mane. Rainbow?”
“Right here, Twilight!” Rainbow walked into the room, sitting down near Twilight and spreading her wings.
“Now then. As you can see, Rainbow here is a pegasus, and her wings are the defining characteristic of pegasi. As alicorns embody all three tribes, ascendants eventually do get wings. I’m told that unlike the other summits, the wings form all at once. There’s no slow growth to go through.”
Rainbow smirked. “Heh. You’re lucky. Pegasi don’t generally get wings large enough to fly until around the time they get their cutie mark.”
“Except when they are very small foals,” Twilight pointed out. “Speaking of, I’m told most alicorns gain wings relatively large to their body size in comparison to pegasi.” She turned back to the ‘audience.’ “At some point, we’ll be going through wing types. Rainbow here has one of the more common types of pegasi wings, and her wings are around the average size for her body.”
Rainbow shrugged. “That’s alright with me. Some of the more rare types are, like, too slim or fat and are good for one or two things at best. Most Wonderbolts have one of the more common types. Means we can do most anything we need to fairly well right off the bat.”
Twilight nodded. “This is true, although Celestia has one of the rare types that’s supposed to excel in all areas.”
Rainbow smirked. “Twi, if you get that wing type, you’re going to have every pegasus stallion from here to Gryphonia falling head over fetlocks for you.”
Twilight’s face blushed beet red once again. “Damnit, can’t I finish one of these without ponies remarking on my sexuality!?”
Rainbow’s wings folded back against her sides. “Hey I didn’t mean--”
“Out! Out out out out!” Twilight planted both forehooves on her, pushing her across the floor and out the door.
“Hey! Wait! Okay, I’m going, I’m going!”
“Argh!” Twilight stomped back into the center of the room. “Next time, ethereal manes.”
