Breach through the fabric barrier

A sudden draft. Air swirling past the corridor led me here, to a massive gray fabric monolith rising from the floor. A rolled-up wool throw blocked the narrow gorge along its side. Unacceptable obstruction. I lowered my head, dug my hind claws into the floorboards, and rammed my chest into the bulky bundle. Grunting low, I drove it aside until the rolled blanket flopped down, wedge firmly broken. I climbed onto the conquered pile. Vantage established. From this peak, the vast open floor lies entirely exposed.
