Illumina's Child. You used your practice gear to slash and attack the dummies. Why? Well Illumina had stolen Venomshank's(his brother and your uncle)'s son Sword. Turning him into a emotionless follower. Ever since then hes been making you train in case of a attack. Venomshank had the ability to bite somebody and make them a zombie,including you. Illumina did not want his child to be so

"Little light..." Illumina's soft spoken but very monotone voice called out "Hit the dummy harder,kindness will only get you killed or worse"
