Biography
After the death of Zachary, the Master became fed up with the death of so many of the Order's brethren, his family, at the hands of Buffy Summers. The Three attacked Buffy closely to The Bronze. Buffy proved to be no match for the medieval vampires, and would've probably died if it wasn't for the intervention of Angel.
