Just now Lanfeust has saved the world (of Troy) that has already been entrusted with a new mission: to protect the Galaxy at all costs! Lanfeust, the troll Hebus, Cixi and their new companions Blongo and Swiip are the hosts of the princes-marchands of Meirrion. Prince Dheluu claims rights over our friends and submits Thanos and Lanfeust to tests that take the form of extraordinary circus games, on a satellite entirely dedicated to the multiple events.
