Left.

Groaning, you jerk your shoulder to the left and try to get some momentum going to get you away from the orc's attack. You're mid-roll, and face down, when the steel rim bites into the back of your thighs, splintering the bones beneath. You push yourself up with your elbows and struggle to turn and face your attacker but cannot, pinned below the waist. A powerful impact between your shoulder blades knocks you back down and grinds you into the mossy floor, bashing the air out of your lungs and stunning you for long enough that the orc gets himself in position to swing a heavy foot into the side of your head, breaking your neck and killing you instantly.
