It tipped its head up, tasting freedom, and then reared itself upwards, head smashing up through the ceiling, glass and plaster hailing around them and littering the floor of the bank. Down on the floor she could see that the Death Eaters had broken through Professor McGonagall's locking charms on Gringotts" doors, and there was a pitched battle going on. The other Order members and the enemy alike paused and stared in shock as the dragon and its six passengers erupted from the floor and took out half the roof, but resumed sparse seconds later.
