Well going with the European theme I can understand, but Hieledran is a very small isolated nation so traveling in and out wouldn't be easy. And with the Blackguard finding out first off they are the hunters and with it being the full moon they would be out in force and with any sign of them in an area the Blackguard would be on the hunt and any "survivors" that they found wouldn't remain that way for long if a mark was found. If you want to keep your character mainly as is I would say taking out the werewolf part. Make your master into one of the Blackguard and make it so your training more incorporated into the lore of Hieledran. Your character would then easily be able to receive the training required to be an assassin (because really there isn't a need for someone based on stealth and speed to be able to lift 300 lbs) and then you would then be able to join the hunters and leave Hieledran as a part of Jocelyn's group.
