What Sara didn't know was that this was no ordinary ring. This ring was as authentic as it could be; the gold was 24 carat and the small rubies on it were nearly flawless. In reality the ring was worth easily a thousand dollars, and she'd gotten it for roughly 25. But that wasn't the real secret of the ring.
Though she had no way of knowing, this ring was enchanted by a Native American shaman, a modern day magician, who happened to be rather embittered about his lot in life. Harnessing the totemic powers of his people, her placed a wolf spirit inside the ring, binding it to possess anyone who wore the ring, making the wearer, for all intents and purposes, a skinwalker, a werewolf.
The moment that Sara put the ring on her finger, she ceased to be Sara at all, at least mentally. The force of the wolf spirit overpowered her mind in an instant, imprisoning her psyche in the deeper regions of her mind.
The wolf spirit smiled, looking around its new surroundings. It looked in a mirror in the hallway, and was pleased with its new host. It knew all that she knew, and had already begun to formulate a plan. It was no mere coincidence Sara had received the ring this day- it was the beginning of a 30 day cycle when the moon was closer to the earth than it had been in 75 years. Now was the time of the wolf. Now was the time to gain minions. Now was the time to restore balance to the sacred lands.
