Magnus follows the blast of sand with surprise, that was certainly new to him. As he turned he noticed the other hound, he had been careless.  He stops as quickly as he possibly could. during his slide to a stop, he spins his sword in his hand and plunges it towards the blinded dog.

No feelings of remorse were in his heart as he attempted to plunge his sword through the blinded dogs skull. If one was looking into his eyes at the time, no warmth would be there, only cold and anger.
