Cassius cobra

Cassius screamed in rage, crouching, and flicked his hand at Mouse. There was a surge of dark magic, a shimmering blur, and suddenly a serpent coalesced from the shadows lying upon the gallery. It reared up for a second, and I could see the deadly outline of a cobra's hood rising a good five feet from the floor. Then the serpent launched itself at Mouse.
My dog saw it coming, sprang back from the serpent's first strike, and then leapt forward, jaws trying to latch on behind the shadow serpent's head. Lashing loops of reptilian darkness whipped into coils that tried to trap the big dog, and the pair of them rolled along the floor, each seeking to grasp and kill the other.

The last time Mouse had growled at anything-for that matter, made much noise at all-it had been a crazed sorcerer who made fair headway toward eviscerating me, and summoned a twenty-foot-long demon cobra to kill my dog. Mouse killed it instead. Then, at my command, Mouse killed the sorcerer, too.
