cassius counterspell

I felt a surge of magical energies. The air around Susan grew darker and then coalesced into a cloud of shadows. Within a heartbeat, the cloud deepened, then solidified into a writhing tangle of snakes of all sizes and colors wrapped all around Susan. The air suddenly filled with the sound of hissing and buzzing rattles. I saw the snakes begin to strike, fangs flashing. Susan let out a scream.
I turned to the doorway and saw the snakeman Denarian standing in it. One not-quite-human hand was held out toward Susan. His serpent mouth was rolling out hissing sounds, and I could feel the thrumming tension in the air between the Denarian's outstretched hand and Susan.
Rage flooded over me, and I barely stopped myself from throwing out another blast of raw spellfire at the snakeman. With that much rage behind it, I'd probably have killed everyone in the room. Instead, I reached out to the air in the hallway beyond the Denarian and pulled it all toward him, the words, "Ventas servitas!" thundering off my lips.
A column of wind hit the snakeman from behind, lifted him from the floor, and flung him across the room. He slammed into the wall of washing machines, driving a foot-and-a-half-deep dent in one of them, and let out a wailing, hissing whistle of what I hoped was surprise and pain.
Susan flung herself onto the ground, rolling, tearing at snakes, flinging them away. I could see flashes of her honey-brown skin and saw the black dress tearing. Droplets of red blood appeared on the floor near her, on her skin, and on the discarded snakes, but they were hanging on. She was tearing herself apart in her panic to remove the snakes.
I closed my eyes for a second that felt a year long, and gathered together enough will to attempt to disrupt the Denarian's spell. I formed the counterspell in my head, and hoped to God that I didn't misjudge how much power I'd need to undo it. Too little and the spell might actually get stronger, like steel forged in a flame. Too much, and the counterspell could unleash the power of both spells in a random, destructive flash of energies. I focused my will on the cloak of serpents over Susan and lashed out at them with my power, letting loose the counterspell with a snarled, "Entropus!"
The counterspell worked. The serpents writhed and thrashed around for a second, and then imploded, vanishing, leaving behind nothing but a coating of clear, glistening slime in their place.
