The person Owen Bertram recommended to William was Preston Barnett.
He was a native from the Southern Border of the Wood Dynasty and a disciple of the Southern sorcery "Five-Spotted Sect." However, he had been narrow-minded and biased since childhood, disliking the orthodox witchcraft of his sect, and instead, was fascinated by poison techniques, which were only considered auxiliary to witchcraft within the sect.
The elders of the sect didn't like him, and as he was a native, short and ugly-looking, with dark skin, a flat nose, and a big mouth, others in the sect didn't want to associate with him either. On the contrary, he enjoyed such loneliness and found a cave in the deep mountains outside the sect to study poison techniques on his own.
