The phases of the moon, and just the moon in general, plays a huge part for the werewolves where I come from. My auspice was determined by the phase of the moon I was born under. I can shift into my other forms more easily under a full moon and less easily under a new moon. I also have to know a certain rite in order to make sure I shift back to human form fully clothed.
Also, many congratulations on having a roof!
I do no mean that sarcastically either. I'm not sure how typing comes across in tone...
