Merlin's Daughter

The Amulet of Merlin has been used by Trollhunters for centuries. Every Trollhunter is given the task to protect it with their life. That has been the way since it was created, and everyone has done it well. When the amulet was created Merlin knew that there may come a time where a second person would need to wield the amulet while the owner was still alive. So, in his spell he created an over-ride key, and tied it to his most precious possession; his daughter. Now, centuries later that key needs to be used, the first ever human Troll hunter is in danger- and Merlin's daughter awakes.
