Firecat 1

A blast of searing fire roared from the heavens and sprayed across the stone under which he huddled. His lungs felt seared by the heated air, and he smelled the tips of his hair burning away.

...

Between the crackling of nearby potted plants that had ignited in the conflagration, and the pounding feet and panicked screams of the fleeing bystanders, Jace heard something new, the sound of claws clacking across the tabletop above him. Something had ridden the fire to earth.

...

A quartet of Jaces lunged from beneath the table, each sprinting in a different direction to take cover beneath or behind some other flame-resistant obstruction, this one a pillar, that one another table. The thing that had skittered across the stone watched all four. Its ears lay back in confusion, and it stretched its mouth wide to utter an angry hiss that was the crackle of a dozen bonfires.

It might have been a cat, this thing, had it not been roughly the size of a hunting dog-and had it not been made entirely of a living, semi-solid flame.
