Extremely big fan of the Witcher Franchise, played the first two games (eagerly awaiting the third), and read the first two short novels that have been translated into English (Blood of Elves and The Last Wish.) 

I have quite an extensive familiarity with the lore of the series, so I could quite possibly help out if you require it in any capacity. 

I'm gonna keep an eye on this and see how things pan before I make a full commitment though!

If I were to make a character I'd go for the obvious class of Witcher...Mainly because I'm very familiar with the role, love playing as a monster hunter, and have role played my own variation of the Witcher in an RP on another forum!
