Sleeping Dragon Stormcloud

Anyone! He is in a prison cave and will have a guard so your wolf could be either the guard or a visitor. He is known as Storm to his captors

Cirrus gazed at a vein of coloured rock on his cave wall. The sunshine outside filtered in only far enough to touch the tips of his paws, and it was only a weak winter sun. He had hours to while away, and contemplate his wrongdoings. Also to nurse his absolute hatred towards the thick giant that had caused his imprisonment in the first place. Goliath had caused all of this, in his mind, and had also been the one to break his leg. That it had been at Heda’s bidding was of no interest to Cirrus. The man did not feel much blame lay at her paws – Heda was doing what any Alpha would do.
 
He wondered when Heda would tire of him. When his drain on her pack would become obvious. Perhaps when his leg had healed and she realised he had no talent. Exhausted by these thoughts, Cirrus drooped over to lay on his side, his once-silky fur matted and dirty now that his cracked rib did not allow him to twist his body and groom. He gazed up at the close ceiling with one liquid brown eye and silently chastised himself for not thinking of a more inventive name.
