Bizarre Mansion
The dog stood up and lazily stretched, then yawned at the group of mages as if it were a lazy dog being told to go for a walk by its owner, but not wanting to. (Author's note: I don't know if anyone else's dog doesn't want to go out for a walk, but one of my dogs prefers sleeping at home.)
One of the mages looked at the dog with anger, unsure of what came over him. He considered himself a calm and rational individual, but now he felt an impulse to kill the dog. The mage pulled out a dagger and rushed to stab the dog in the head.
Splash!
The sound of flesh and blood, along with the splatter of red blood, filled the area. However, instead of the dog's head being pierced by the dagger, it was the mage's arm that was suddenly ripped off by the dog's sharp fang.
"Arrrrrrrrrrrgggghh!" The mage screamed in agony, looking at the dog in disbelief and terror.
