The dragons that Georgie had summoned were quite tiny, but that was not a problem. They were very well suited for the occasion, because large dragons would not be able to help them much in this situation, even if they were successfully summoned. The ice walls were over thirty meters tall, so there were a lot of ways for things to go wrong - They needed precision to get out of here, and not brute strength.
The tiny dragons pierced through the ceiling of the ice labyrinth successfully, and they did so elegantly. They cut multiple small holes through the ceiling, to create a very-much controlled exit point. It took a while for them to achieve this result, because the exit point ended up being thirty-five feet wide which was exhausting to achieve, and it was that wide, because they were counting Georgie’s wingspan in the equation!
