The docile Bomkin named Nibby is recruited to fight the Dagons and protect the Kingdom of Vas, but fears leaving his family home in Landa. He learns he can be an explorer instead and takes off on the adventure of his life, seeking the Crown of Ahran and hoping to find his father, Loqan, who has been missing for a decade. As Nibby travels, he acquires new friends, including the girl Uji, who becomes his travel companion, along with others. Aboard the Quirk, Nibby and his crew, led by Captain Smiles, search for the crown, facing shifty Grks, fearsome Dagons, and treacherous trolls.
