I have been in the Refectory area for two days now trying to find the key to dropping the Gateway to continue on from the Library. I find the glass dragon claw on the floor I suspect it was supposed to be on one of the pedestals that would trigger the gateway. But have gone through here about six times now and the glass claw is always on the ground. I suspect that the Draugar are blasting it to the ground with their shouting. Any thoughts or suggestions?
