Headmage's Summoning

     After they finished their food, the four walked all the way to the Headmage's office. When they arrived at the door Duece knocked before opening the door a little. "Headmage, may we come in?" He asked.

    "How's it going, sir?" Ace said as he shoved his way into the room.

    "Ah, thank you for coming." Crowley said as they entered the room. He gave them a moment to sit down in the seats across from his desk. "I'll get right to the point. Now that the Heartslabyul incident is behind us, I wanted to give you a proper debriefing on the matter. If you're to become mages, you need to fully understand the malady that befell Mr. Rosehearts."

"You called it 'overblot,' right?" Deuce asked.

"Yes, that is correct."

"My brother told me a little about that." Ace said. "He said that could happen to anyone who builds up too much blot. Sounds like Cater was pretending much on the nose with 'berserker mode.'"

"Yeah, but what is 'blot' anyway?" Grim asked.

"How does blot work and junk?" You asked.

"Ah indeed." Crowley said. "For the sake of the two of you, it would behoove us to start with the basics. I shall teach you all you need to know. Charity, thy mane is Crowley!" He cleared his throat. "Now, 'blot' is a form of waste that is created as a byproduct of using magic. Just as cars run on gasoline, and in the process expel dangerous gases as exhaust, casting spells consumes magical energy, and in the process, expels blot."

    "So magic has a carbon footprint."

    "Quite. Research into the nature of blot has been conducted since time immemorial, and yet we still understand little about it. All we know for sure is that it is terrifically toxic, and excessive amounts can wreak havoc on a mage's mind and body."

     "I guess that's why Grandma was always nagging me to not overdo it with the magic, huh?" Ace said. "Here I thought she just didn't want me to break stuff."

     "This sounds similar to what (Y/N) says about being careful with her Quirk." Deuce said.

     You nodded. "Drawbacks can be deadly if you push yourself too much." You said. You saw Crowley looking confused. "Similar to blot, a drawback is the side effect of a Quirk. Depending on the Quirk, there can be a variety of drawbacks. It explains why I was tired after the fight with Riddle."

"Power and peril are two sides of the same coin." The headmage said. "Even the greatest of mages cannot cast spell after spell without consequence. I guess the same principle applies to those with powers."

"So you're tellin' me I'm gonna get sick if I keep usin' magic whenever I want?!" Grim asked, the fur on his neck standing up. He was getting worried about how he can become the best mage in the world if he keeps getting sick from blot.

"Not necessarily. Perhaps a demonstration would prove more efficient than a mere explanation. Ghosts, assemble! I have a job for you!" That's when two ghosts appeared, next to Ace.

"Huzzah! You summoned us, Headmage?" The shorter of the two asked.

"Not these guys again?!" Ace said.

"Would you be so kind as to help me put these young students through their paces? Miss (L/N), I want you to take a step back. I've already seen how bad things get for you and I don't want to send you back to the nurse's office." You nodded and went to stand next to him.

"T-This seems like a bad idea." Deuce said.

"Yeah, okay." The taller of the two said. "We'll go a round or two with em."
