(210) Chains?
Filthy crept silently down the tunnel with Geth trailing ten paces or so behind. He would typically prefer to scout alone, but he would need Geth's healing to get him out if the situation took a precarious turn.
The noises that he heard were constantly changing. At first, he could only hear the periodic sounds of growling coming through the tunnels.
The deeper they explored, the more he could listen. Between the angry and resentful growls, he could hear whimpering and the clinking of metal.
'What the hell is that?'
His ears twitched as he strained, an annoying quirk that began when his senses hit a certain level. It wasn't worth complaining over, though.
If he closed his eyes, he could recreate a blurry image of what he heard with his heightened senses. This quality had helped him many times when sniping a well-hidden target.
After walking for a few more minutes, Filthy waved for Geth to stand back. The origin of the noise was close.
