Deal (part1)

"But… how?" Aito asked, more in actual astonishment than for the sake of getting an answer.

He thought that at first, Valinar, the dead goddess of bravery, had given him some kind of magical metal to help him in his endeavor. The kind of unbreakable, legendary, super-duper-killing-god-kind of metal—at least he had hoped so. Well, in a sense, it was a magical rock since it could repel aura.

The minerian said there was a high possibility of a living thing hiding at the center of the stone as if it was an egg of sorts. Furthermore, the metal protecting whatever was inside could regenerate. Meaning it could only be something important, precious. He certainly hoped it wasn't some kind of industrial toy hiding inside. 

If that were the case, he'd sign a complaint to the goddess of bravery. It'd make for a poor reward, after all.
