the dragon whisperer and the seven kingdoms

Callan was a very sad boy even though he had his dragon friends with him he never felt like he had a purpose in his life then one day a map blew in his face and saw it was a map to seven kingdoms and saw that these kingdoms were never united and saw every single one of them held a part of the dragon realm then Callan got an idea to reunite the kingdoms and explore the realms when he told his friends they we're excited so they headed out on to an adventure to unite the seven kingdoms but what they didn't know was that many dangers we're ahead of them
