As Lucas and Clara set out to investigate some mysterious happenings in Wrenly, they find a Pegasus that is lost and in danger. Will the two friends be able to help the mystical creature find its way back home to a floating castle high above in the clouds?
Mischief-makers Prince Lucas, his best friend Clara, and Ruskin the scarlet dragon learn to respect the hard work of others when they are sent to Flatfrost to fetch more ice from the giants who live there.
Eight-year-old Lucas, Prince of Wrenly, is eager to explore and Clara, daughter of the queen's seamstress, knows the kingdom well, so they team up to find a lost jewel and visit all of the land's main attractions as they search.
Lucas and Clara are floating on a raft when a wave casts them into the sea, where Lucas catches a glimpse of a coral kingdom and a dark-haired mermaid helps him, but when his father, King Caleb, hears of this, he scolds Lucas and tells him he has broken an age-old pact.
