Vengeance, the Master's Death

Caleb accused his brother Ethan of a murder Ethan had not committed. Master Elder Silas cut off his own arm over the charge and destroyed Ethan's martial arts. After the punishment Silas taught him the school's secret Dragon Tiger Fist and sent him down off the mountain, and the two set a term of three years. Ethan came back when the three years were up. Silas was dead by then. Ethan looked into the circumstances, found them irregular, and opened the grave to examine the body. Silas had been poisoned. Before Ethan could name who had done it, outsiders arrived at the Dragon Tiger School demanding the Dragon Tiger Fist, and a match was set with no limit on what could be done in it. Caleb got poison into Ethan during the match.
