Breaching the Perimeter

Floor patrol got stale, so I marched straight toward the outer boundary. Found a giant barrier—thick wooden slab locked tight into a metal frame! Solid perimeter wall. Lowered my shoulder and rammed it full force. THUD! Rattled my skull, but the timber didn't groan or shift a millimeter. Heavy build. Respect! Dropped low to scout for weak seams. Spotted a dense black bristled mat pinned beneath the gap, tough as wire mesh. Dug my heavy boots right into the stiff bristles and stomped hard. Good traction. This doorway is a proper fortress gate!
