I imagined modern era just because I wanted to include myths across the world. The main character is a species of werewolf from the northern Inuit mythos. To be more specific it was an Amarok, they are among the rarer forms of werewolf. They are called hunters of hunters so more often than not they are assassins or bounty hunters for the world of legendary creatures. It stuff like that I work on when I'm not working on my main piece.
Awesome concept. Sounds like it's worthy of at least one novel, though I can see it working in an interesting fashion if it were multiple novels where each had a different main character that it followed.
Since you mentioned werewolves and Inuits, I'm reminded of 30 Days of Night... about vampires, but I like the idea of werewolves in a similar environment better.
Though I'm guessing that by it's nature, the tone you're striving for is a more action than horror? If so, I can also really see it working as a comic book or graphic novel.
Well, like I said it is still pretty early in development, so I was really unsure of the direction. I really only have a few speciations of vampire, werewolves, and some ghosts. This seed came about maybe a few months ago. I actually imagined it a graphic novel too sometimes.
