At the back of the cell, as far from the iron bars as possible, Adrian sat with a thin blanket around him, his back against the stone wall. He's seen no sun, had no fresh air, hadn't seen any plants, not even moss, since being brought to this awful place. The iron barring their cell was poison to Adrian, he didn't dare go near it. After a few days, the entire place seemed like poison to him. He grew weaker, didn't bother moving unless he was moved by the stone men.
Adrian did keep some small measure of determination. He'd maintained his human form throughout. He speculated he might be a little less sensitive to the iron this way. Mostly, he didn't want to exposed his wings, not after already having blood and skin and hair samples taken. He worried that their captor or captors might want more. They might want his dust, which he would not give. His resolve stayed strong even as his body weakened.
It didn't seem worth staying awake anymore, and Adrian had long run out of anything to say. He was startled back into awareness from time to time, and was again as he heard Ashton make grumblings against their stone captors. The noise had almost sounded like words and Adrian leaned forward from he wall, his brow furrowing in curiosity. "What was that?", he asked in a slightly raspy voice.
