Impact

From publisher blurb:

Engine of Destruction

Abel Shepherd joined the army to escape a troubled childhood. During combat, he was wounded and found a vine-covered temple to hole up in. Touching the wrong gem, he was trapped inside. Meanwhile 50 years passed. Transformed by the magical cocoon, Abel had become an engine of destruction. He emerged as Impact (PL 12), and is now compelled to seek out those who had wronged him in life and vent his wrath upon them.
