So we're all just outside Hagrid's Hut, perhaps learning to ride a wicker hippogriff, or maybe we're by the stone stage, when something goes horribly wrong and we're all called back to Hogwarts. So we run in through the gatehouse entrance, over the bridge, and eventually into the Great Hall where we get informed that Hagrid's latest "misunderstood" creatures have gotten loose...
Then we get recruited to help round the creatures up so we meet outside the forest where someone multiplies Hagrid's motorbike for us and we all go for a ride.
Right? :grin:
