The human didn't notice them.
Hiroshi realized it fast and made a sharp gesture with his hand. Stay still and don't move. The others read it immediately. Nobody breathed too loud.
The human walked into the room. He was tall. Well dressed compared to where he was. A long coat, dark colored, and boots. He wasn't young but he wasn't old either. Somewhere in the middle.
He wasn't looking around the room.
He was talking to the goblin.
Not in any language Hiroshi recognized. Something guttural and clipped. The goblin was listening carefully, nodding along, holding the torch up. The human kept talking. Calm and steady like this was a normal conversation in a normal place and not a goblin treasury underground.
