Oathbringer - Szeth

Szeth punched him across the face, his arm leaving a faint afterimage. He grabbed the sheathed sword, ripping it from the weaker man’s hands. Though the weapon often seemed too heavy for its size, it now felt light in his fingers. He stepped to the side and swung it—sheath and all—at his enemy.
The weapon struck the convict’s back with a sickening crunch. The poor man splashed down into the lake and fell still. Szeth shook himself. Had he killed the fellow after all? Szeth knelt and pulled him up by his matted hair. The convict gasped, but his body didn’t move. Not dead, but paralyzed.
