It Seems Like The Facts Are A Little Jumbled.1. Wolves don't howl at the moon. That's a common misconception. They howl to call to other wolves. Like screaming in the middle of the woods "Hey guys! I'm right here!" Sound travels better when it isn't trying to go through a forest of trees; hence the way they tilt their heads. Neither do we. If any of you were real, you'd know that. It's all a part of communication. That's it.
2. It's all completely genetic. Someone, somewhere in your bloodline was one and now you are, too. You can't drink a potion, cast a spell, or get bitten. I'm sorry, I know how glamorized this life seems, but it doesn't work that way. My grandfather was one, so is my aunt. It goes back for hundreds of years. Also, remember that wolves can tell other wolves apart out of a crowd. It only takes a few messages back and forth before it becomes blatantly obvious that you are a liar.
3. Only about 99.7% of the people who are writing stories are real. I've yet to be convinced otherwise. I'm a kind soul, but I don't take kindly to humans who play pretend with something that is very, very real. For few of us, this is our lives. We don't get to go back to 'normal' once we log off.
