After his dad's boat crashes, Ed finds himself on a strange beach. He meets a girl - headstrong Steff - who doesn't know where they are, either. As Ed and Steff explore, they discover the deep lore of this new realm. They meet a pack of wolves with a secret and an armoured pangolin called Astolpho, who reveals the only way home involves a dragon who lives at the top of an impossibly tall, rocky spire.
