He stopped when the ring stopped and when it tightened, Crowley scowled to himself. And Crowley, though his power was constricted, pressed against the circle -- a constant chaotic swirling of power attempting to force itself free.

A warning just as much as the tightening. The moment Crowley was free, whoever was doing this was going to face his wrath.

"I'm beginning to lose my patience," the demon hissed, tensing at the feeling of power, the sudden smell -- his eyes narrowing slightly as he memorized the feeling of both. But all the same, Crowley kept walking -- until he realized that the circle was still maintaining itself and by the looks of this alley and the fire escape, it wasn't going to be anything good, he abruptly stopped walking and withdrew his hand from his pocket, snapping his fingers neatly.

And, suddenly, there was a snarling at his side, outside of the circle -- a bristling hellhound, massive claws digging into the ground as she pushed herself forward.

"Find whoever is doing this and rip out their heart," Crowley growled. "Save their soul for me."

And the hellhound immediately padded forward, teeth showing as her hackles rose, to hunt Magneto down.
