Ok, so I'm going to have a pretty cliche werewolf character. He's a Nord who joined the companions and became a werewolf, he's a pretty good guy too. But every night he transforms into a werewolf and goes into a bloodlust...

I'm finding trouble giving him a background though, how did he get to Skyrim? Why did he got to Skyrim? Why did he bother joining the companions?

If anybody can also made the idea a bit better please feel free to point it out.
