Nikolai Sobakov

Nikolai, originally a regular human from Epois, became a sailor in hopes of travelling Fortaare and finding a new nice place to settle in, eventually stumbling upon Saromara, a land mostly inhabited by humans and other primates. They welcome him in and treat him well, he does a few transactional jobs with his sail, mostly just hanging around the trade harbor, until one day someone knocks on his door to ask him if he wants to contribute to a new scientific experiment. 

He accepts, thinking that it's a harmless one, but when he gets in the governmental labs, he notices that something is wrong. Saromara looks like a typical republic but under it's seemingly tame overcloth, there's a corrupted government doing secret bioengineering experiments. Nikolai was there to try a new "anecdote for a poison" which turned out to be another experiment trying to bioengineer stronger units for battle, thus turning him into a werewolf. After this, he loses all control of his bodily autonomy, and goes all feral, hurting both himself and the clueless scientists nearby. In this event, he loses his index finger. 

After a few doses of sleeping juice, he turns back to "normal" but still keeping his werewolf genes, he learns to control them over time. He actually benefitted more from them than he could ever imagine. Though he still sometimes has anger bursts and destroys a vase or two, he's calmer and more balanced for the most part. 

The extra strength that comes with his wolf form definitely helps him when blacksmithing tough minerals and materials, and the hunter instincts help him catch fish while swimming, kinda like how bears catch their salmon.
