Bearded Man:  "If you even dream about scramming, things’ll get messy."

Subaru:  "Yeah, yeah, I know. I promise I won’t run away. You can keep my hands tied. Just let me walk deeper into the cave. I wanna talk some things over with Liliana.”

Bearded Man:  The bearded man looked at Subaru and mused over the proposition for a while. Then he sighed and said, “Yeah, it’s a stalemate otherwise… Fine. It’s always easier to convince a person if you get her friend to do it. It’s better for all of us.” The bearded man untied Subaru’s feet.

Subaru:  Finally free to move again, he stretched out his stiff limbs, letting the blood flow through them before standing up. “You come with me, okay? Nothing good will come of staying here drinking.” Gesturing over his shoulder at the man with his chin, Subaru began to head deeper into the cave, his hands still bound. As he walked, the cold breeze rustling his hair, Subaru squinted his eyes shut in the light of the ragmite. Then he cautiously opened his eyes into the light and saw it. “So this is it…the stupid metia that’s unlocked by a song.” Before Subaru’s eyes stood a black wall blocking the path deeper into the cave. The wall obstructing the stone passageway had geometric carvings on it, and in the center, a blue crystal was embedded. The wall itself seemed to be made of a material similar to iron, but it was a little too black and a little too mysteriously imposing for that.

Bearded Man:  “It’s rigged to move only when certain conditions are met,” the bearded man explained. “It doesn’t always have to be a song, but this door is rigged to open only when this girl here sings the song.”

Subaru:  “Are you sure Liliana has to sing it?”

Bearded Man:  “It won’t open if anybody else sings it. Our traitor had her sing into the metia and used that to put the magic seal on this cave. That’s why only the girl’s song can open it.”

Subaru:  Hearing the bearded man’s explanation, Subaru approached the metia again.
