Assassin
A great wizard could not rise without the support of an extremely influential power. It was a pipe dream to achieve such success alone. Were he to try to build up his power and wealth through underhanded means, he would obviously provoke many people.
In comparison, the Faulens had only met with a small inconvenience. Even if Leylin broke away from the family, he would still run into the same problem when trying to make a name for himself.
It was needless to say that his identity as a nobleman was rather decent. At least it allowed Leylin to travel unimpeded in any place where human civilization gathered. He couldn’t bear to give that up.
With the speed at which his strength was improving, the Faulens would one day be unable to meet his demands, thus he had to expand the interests of the family.
