Urumviel

A breath later, glass shattered and fell. Dark, inhuman forms dropped silently from overhead.
I picked the outermost of the invading Denarians, the one farthest from the center of action and attention, pointed my staff at him from my hiding spot amidst the green, and snarled, "Forzare!" unleashing a moderate effort of will. Invisible force caught the shapeshifted fiend as he was falling. I never got much of a look at him, beyond the fact that he had a lot of muscle and a ridge of leathery plates running down his spine.
Muscle doesn't do you any good in free fall, no matter how many Fallen angels you've got inside you. Unless you've got some wings to put it to use, you're in the hands of Mother Earth and Sir Isaac Newton.
I wasn't trying to smash him into the middle of the lake. I applied just enough force to alter his trajectory, shoving the falling Denarian thirty feet off course, and he landed in one of those beams of titanic energy.
There was a flash of white light, a brief shadow of a human skeleton burned onto my vision, and then a white-hot something went spinning out from the beam. It landed in one of the pools in an angry gush of steam. The dolphins darted away from it.

"He hunts us," Deirdre said, "while she forces us to focus on piercing a veil. They work too well together. He's killed two of us. Three if you count Urumviel."
Tessa bounced the silver coin in her palm. "Urumviel's vessel may have been killed by his own idiocy," she said. Her insectoid eyes seemed to narrow. "Or perhaps the wizard managed to return before the Sign was raised."
