Arrival.

As he arrived at the site, he met a mature looking woman waiting for him in front of a house, accompanied by another girl looking in her teens. He thought to himself, "Am I really at the right place?".
"Good Afternoon, my name is Eleanor, a care taker of these children inside the house, will you be the one who will be working with us?" she asked.

"Uhh, yes, but what kind of job am I supposed to do here? I was told I would be managing the weapons of the army, not taking care of these children."

"Hey!! Don't look at me like I'm a child! My name is Alice! And you will be taking care of us!" she shouted.
"What do you mean I'll be taking care of you?" he asked.
"Yes, that's your job here, please take care of us." she answered with a smug face.

There were a lot of children living in that house. Alice was the oldest, then Lucy was the second oldest, there was also Rory, Isabel, and Amelia. There were too many to name each one.
After introducing me to the children, Eleanor guided me to the storehouse of the weapons. The weapons that I saw, was the weapons we were using back then.
"These.. weapons? The Carillons? What are they doing here? These were special weapons that only chosen humans could use. So, with the humans gone, who's fighting with them?" William asked.
"You already know don't you?" Eleanor answered.
"Tell me." William asked with a pained face.
"You see, those girls are fairies, they have imitated humans since ancient times. They can use human weapons as a human would. And their bodies were made as weapons to be expended in battle, and they don't fear death. You wanted to know. Now you have the answer." Eleanor answered sadly.

Hearing about little girls, who are weapons of the army against the beasts, I was surprised, but hearing about it, I had no other choice but to stay silent. When I was at the orphanage around 500 years ago, we were always accepting quests to battle monsters and earn our living. Maybe that's the reason I am not that much surprised.

Now I am in this world, living for 500 years, no human could live that long. But when I was fought a beast, I lost the battle that caught me frozen in one of their petrification attacks. That's how I lost and fell into an eternal slumber for almost 500 years, until I got discovered by the group of salvagers by the team of Grick.
