The Dragon's Egg Is Stolen

The dragon's egg is stolen. Bloodraven has several spies amongst you and he himself is among you. So why not just let it be that then? He's got to blame it on Glendon Ball, which is kind of odd to me. Partly, they are trying to get rid of him because he's winning and they can't have him win yet. They don't want him to fight in a trial by combat. But when could he have snuck off to do this? It's not very feasible. If someone had been like Brinkish, where are the bodies?
