Perhaps a mage or necromancer picked up one of the shards, trying to be more powerful? Don't know.....Anyone? Perhaps Ocato will be good indeed. He's quite important and a strong mage. Only problem would be, that he will be replaced (If chosen for)and thereby losing his title. :D Perhaps Martin could handle that, or we need someone else important maybe for the necromancer thing, they are aware of the power the amulet holds, and are trying to extract blood from it to try and overthrow the empire or make one of themselves the emperor, or bring back the king of worms or something like that...
