Wendy

Wendy picked up the coin and scanned it carefully. Without a doubt this was no coin the young Dragon Slayer has ever seen before. She was alone. So what should she do? Well she could just toss it away...but is was kind of rare after all. Maybe the Master would know something about it. She should just ask him. But as she left the guild a while ago Makarov seemed to be busy. I couldn't be helped...she had to keep it for a while.

suddenly the world went black for a few seconds. Wendy thought she could hear some stuff from certain magicians in the guild but...there was something fishy about it. First: She couldn't point any direction where the voices came from. Second: She had absolute no idea what exactly was happening. Soon the world came back. But what Wendy didn't know that moment was that she had switched bodies with someone.

Who switched bodies with Wendy?
