Ramiel emerged from the darkness in the smallest of the passages. The tunnel complex was underground, so the former hunter could literally appear anywhere as long as he had enough mana.
He waited until Maya joined him and wordlessly moved ahead, armed with twin blades. He didn't need a light source. Spending a small amount of mana, Ramiel could see perfectly in the dark.

The former hunter offered Maya torches, but she politely declined. The vixen studied the element of sound and developed something like echolocation. To some extent, she " saw " farther than he did.
