Okay, so I just assumed that Owyn would have woken up without any gear. Maybe the Kobolds couldn't figure out how to take his armor off? Does he have everything else too? Or do I need to find it to reclaim it?
They took everything except what he was wearing. Armor isn't going to hurt them. They didn't figure it was worth him waking up while they were doing it. If you'd rather not have it,that's fine. We can handwave it.
Up to you. You aren't technically hidden (and the tower is dark, so Beturea's torch is going to stand out). My next post the kobold will see you, so you can decide if you want to talk or attack, or anything else you can think of. No one will be surprised, but we would roll initiative.
