Tall Tower, Secret Passages and a Dragon Egg(Closed to Ripple)

Riza was lay in her bed in the Hufflepuff common room. The lights were out but she lay there, thinking. She had been to her first Astronomy lesson yesterday along with all the other first years... and the view from the tower had been amazing. The question was, could she find her way back without a prefect's help?
Sitting up, Riza looked around. There were a fair few people in her dorm, including Alex whom she had met at the sorting ceremony and had gotten along with like a house on fire since.
Getting out of bed, Riza crept towards Alex's bed.
"Alex~" she whispered, her normal, cheerful tones still evident in her voice as she checked to see if her friend was asleep or not.
