There is a door in the upper level that leads outside onto a balcony. But once there you get stuck. Apparently teleport doesn't work either.

Sorry about this, it was supposed to give you access back down to the main courtyard. I'll get on this and send in a fix. It might be about 3 weeks until this gets fixed, so please avoid the upstairs exit in Dragonspear for now. Thanks.
