Eren froze the moment he heard a disembodied voice call out to him, feeling a cold shiver crawling down his spine. Usually he would have just ignored not being alone in the basement, but the strange dissonance of te voice and where it had came from - too loud and somehow sounding as if it were coming from below - alarmed him.

For a moment his eyes traveled down, but there was only solid concrete below his feet. And he hadn't noticed an hideaways or trapdoors further down either...

Squinting his eyes in a vain attempt to see better in the darkness, he made a careful step forward, not answering the call.

"....." Was it just him or did his breath echo abnormally loudly?
