As you are chucked into a large cell you hear the two that threw you in shout "Have fun with that beast down there!". The door slams hard as you look over and see a large, lumbering anthropomorphic dragon chained to the wall. Enormous and lightly muscular standing over thrice the size a human would be. 6 heavy shackles around him. And a key for them on the floor. His voice echoes out

"Ah great! You know, being chained here is kinda boring.... Rather than me breaking these shackles myself do yourself a favour and how bout you get these chains off huh?"
