The necklace we know to be some sort of key.
All we know about this amulet of is that it belonged to the paladin’s father Sir Birchwood. In the notes that was found in the Arch-Paladins house, you find that it is important and the most be brought to the king. We also know that it is some sort of key. It is a silver amulet with deep scratches the long side. The deep red ruby sets within the middle. It might seem strange but, if you gaze into the center of the ruby you swear you can almost see a flame.
