Duke Henry Knowles is a high-ranking Anatoray noble who fathered Count Knowles. In a duel with Alex Row, his son was defeated. Later on, at an auction at Horizon Cave's black market, Alex appeared. The duke had the chance to seek revenge for his son's "unjust" death. He captured Alex at gunpoint but there was a power outage when bombs destroyed the generators of Horizon Cave. During this chaos, Alex killed some of Knowles' men and escaped.
