To be fair, Skull didn't plan on any of it.

He had just wanted to give the people struggling like he had been a chance. He had wanted them to grow, to flourish, because for every one person he sent back to his family, he found 10 cases of civilians dying. And for every 10 deaths he discovered, he found 5 civilians forced to join Famiglia against their wills.

It enraged him.

So, Skull took those he could and he gave them over to his family because he knew his family would let them go after teaching them to survive if they wished to leave.

The end result was accidently creating a safe haven for civilians. And the civilians that left his family would inevitably find others and bring them to where they learned…

Skull didn't plan any of it, but he had accidently become the head of a movement to gather and teach civilian Flame Users.

Not that Skull realized any of this, until he made his monthly trip back to his family- an actual visit and not just him bringing back 'strays' as Valkyrie liked to call them- and found them much, much, larger than he remembered, with faces he recognized, and some he didn't.

Faces that all knew who he was.

His teacher had found him, Valkyrie laughing and bright eyed. "When I let you walk out that door to gather information, I did not expect you to double our numbers within the first month."

He remembered asking "...I doubled the numbers?"

"Well, by this point it's more tripled the numbers. We've had to break into smaller groups so we didn't draw attention to ourselves. The first civilians you sent to us were taught and then they left, only they brought others back to us as well."

Skull had been shocked. That was not his plan. Had never been his plan. To learn that the random act of kindness had spiraled so far, that those he had helped had then gone on to help others…

It had only been the start of it.

"Have you seen the Library yet?" Valkyrie's voice was amused at the sight of his surprise, even as she began to lead him forward.

Skull had turned to face her, confused "The Library?"

"Mmhmm...you started something with the civilians." Valkyrie smirked at him as she pushed open the doors to a small building. "It's not big yet, but it will grow."

Skull had stilled in the doorway, staring around him.

Valkyrie was right- it hadn't been big then, but it had been much bigger than Skull would have expected. He would come to find that in writing his experiences down in a journal, and then sharing that journal with the others he had planted the idea to write their own learning experiences down to share with others.

The result was the Library- where the journals were copied and left for the family to use and read. Each of the journals were color-coded by Flame type for easier identification.

Skull spun in place, his eyes widening as he saw the extent of what a simple action had caused. "This...this is…"

Valkyrie nodded "It is, as of this moment, probably the largest collection of knowledge regarding Flames apart from the Vongola itself." Skull turned to stare her down- even as new to the Underworld as Skull was, he knew of the Vongola- and Valkyrie's lips pulled into a larger smirk "and," she added "It is probably, in a sense, the most unbiased of all Flame Knowledge."

Skull reached for the nearest book, a bright crimson and began flipping through it curiously even as he asked "How so?"

"Well," Valkyrie answered as she reached over his shoulder to pull down a cool blue journal "The people to write this down, are all civilian in origin. So- in a sense- it is unbiased. They have not been raised to believe certain Flame types must be used in a certain way, or act in one particular manner. Each of these journals carries the way that particular user learned. And unlike most others, this collection of learnings is open for everyone in our family. We have a library, and we do not limit what the others learn by their Flame types- who is to say that a Sun won't learn best the way one of the Storms did?"

Skull is silent, the far-reaching consequences of his choice sitting in front of him, in their beginning stages, but even now Skull knows this will shake the foundations of the Mafia.

And he grins.
