Michael vs Kelpie

Two more strands whipped up from different angles, one seizing Sanya's upper arm, one wrapping around his face and skull, and jerked him halfway from the boat in the time it took me to shift my weight and reach for him. I managed to grab one of his boots before he could be pulled all the way over the side into the water. I planted one foot on the wall of the boat and hauled on Sanya's leg for all I was worth. "Michael!"
The boat's engine coughed, turned over, stuttered, and died.
"In nomine Dei Patri!" Michael roared as Amoracchius cleared its sheath. The broadsword flashed in a single sweeping slash, and severed the strands strangling Sanya. The edges of the slashed material burned away from the touch of Amoracchius's steel like paper from an open flame.
I dragged Sanya back into the boat, and the big Russian whipped his saber from its sheath just in time to neatly sever another lashing brown tendril of animate fiber. "What is it?"
"Kelpies," I growled. If they tangled up the blades of the engine our boat wasn't going anywhere. I howled at Rosanna, "Come on!"
