what is the definition of locomotion

Tim Logerquist was a man with a mission. A mission to develop a unified partnership with like-minded Baptist churches dedicated to advancing their collective mission under one association. It would please take a clear, concise mission statement that would reflect his true purpose and engage the hearts and minds of other ministers. William and the friend Jason bring their bicycles on the attic, shrink themselves, and embark on a journey. They meet Sir Simon because he is getting ready to leave for the tournament, and so they stop at his castle. They spend more time a boy plus a girl with the castle and together. The girl tells them of an omen her grandmother, Calendar, kept repeating before she died. Sir Simon sent Calendar away for the convent as he thought she was crazy and he does not believe the omen. Few accept it but Calendar's granddaughter does. Jason and William believe it too.
