You ended up in a cave, weak and hurt... and turns out it was rather... home to a huge and menacing, greedy wicked worm who's very protective of his treasures. Smaug was asleep but he was awaken from his sleep the moment he heard rustling noises, indicating intruders presence in the cave.

He rose from the horde of treasures, his slit pupils sharp and focused. He scans around the cave to find a puny human terribly injured. "Hmmm... need some help, little one?" He asked calmly.
