Silas

Silas is a genius, yet the line between genius and maniac is often blurred. His obsession with metallurgy drives him to extremes: the extremes of the humanity, the extremes of death.

Before meeting Izold, his best test subject was himself. After doing experimental surgeries on numerous bodies, he concluded that his own body was the closest thing to a perfect test subject. Izold could be considered Silas' second best option: Izold was stronger than most people, desired battles, had a potential for violence, and had an unbending will. Izold also enabled Silas to experiment more freely. Some experiments would put the subject into a coma. When doing such experiments on his own body, Silas would not be able to record the statistics accurately.

A successfully augmented Izold could be the best proof to justify the claims the Metamorphs. Silas found great pride and satisfaction in Izold, his masterpiece. After the experiment, the fates of the two are closely bonded.
