“The set is considered one of the most unique sets, including many firsts. For example, this is the smallest ship with a mast in the LEGO Company's history, as well as the only Wyvern dragon designed. Besides that, it is the first dragon design to step away from the Dragon... More Masters one pieced reptiles. Just like every other set in Vikings, its villainous beast is made up, in part, by multiple TECHNIC pieces.”
