Rodney Rathbone , tries to find the stones before the evil Lord Vampyre uses them to eclipse the sun forever . Description . All the Monster Fighters sets follow a similar pattern . Every one features a lair / vehicle of some sort for a monster with a moonstone somewhere in it and a vehicle for the Monster Fighters .

The largest portion of 9468 Vampyre Castle is a large castle , although it also includes a car driven by Monster Fighters . There is no particular color scheme for the theme , although grey and black pieces are featured prominently in many sets , and every one except for 9461 The Swamp Creature and 30200 Zombie Coffin Car contains at least one glow - in - the - dark part . Though each set does include a color scheme to match either the monster or its background . Background . Lord Vampyre , a powerful vampire , was pestered by his wife to get her a Moonstone , but when Lord Vampyre finally found it , he realized the magical power it possessed and decided to keep it for himself . If six of them were brought together ( though there are actually seven in total ) , they would eclipse the sun and turn day into night forever , so the monsters could roam freely , and they could get to the minifigure realms . To defend the earth from this new spooky threat , Rodney Rathbone put together a band of monster fighters to retrieve the stones before Vampyre collected them to unleash their power on the world . These monster fighters include Frank Rock , Major Quinton Steele , Ann Lee , Jack McHammer , all with monster archenemies and personal vehicles . Story . " I am writing this journal entry tonight with the grim knowledge that it may be my last chance to tell the world of my newest and most dangerous mission . In just moments , I will be embarking on a perilous journey into dark and scary places where mortals and minifigure s are most unwelcome . " " It was just days ago , when my keen detective work uncovered the diabolical plot of an evil mastermind - - Lord Vampyre . For centuries , he has been slumbering and plotting inside of the darkest dungeon of the biggest castle in the Monster Realm . When he awoke on the full moon , Lord Vampyre once again rose to power as the leader of the monster army , and unveiled a plan to turn day into night forever , unleashing the land of monsters into our world . Now , we must travel deep into the Realm of Monsters to stop him . " " It all began with a curious jewel called a Moonstone . At the coaxing of his bride , Lord Vampyre scoured his lands to unearth this precious gem . But instead of giving it to his beloved as planned , he soon realized the magical properties of this strange stone . Lord Vampyre locked himself in his castle , and set to work on a machine that could tap into the powerful magic of the Moonstones . Alas , it was completed . Located on the highest tower , it lies waiting for all six Moonstones to power its magic and eclipse the sun forever . " " And so , he mounted a search for every Moonstone in the Monster Realm . As fate would have it , I had been entrusted with the secret locations of these Moonstones , hidden centuries ago by my great , great , great grandfig to protect the world from a disaster such as this . They lie in the furthest corners of the Monster Lands , guarded by ghoulish creatures , in places no one dared to go . The Swamp Marsh , in a secret compartment of the Mummy ' s chariot , the deep , dark Forest , the Crazy Scientist ' s underground laboratory , the Ghost Train , and the ghoulish Graveyard . " " We must take them before Lord Vampyre can get his undead hands on them . Time is short . The monsters are very close to collecting the remaining stones , and there is just one hope left : a band of heroes who won ' t let the lights go out without a fight . Major Quinton Steele . . . Frank Rock . . . Jack McHammer . . . and Ann Lee . Who am I ? I ' m Dr . Rodney Rathbone , of course , leader of this mission . Together , we are the Monster Fighters . Join us , if you dare . "
