wind vs cassius

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.
