In the beginning Pelias and Aeson fought and Pelias kicked Aeson out and off the throne. He threw Aeson in jail and became king. Pelias felt no pity whatsoever for Aeson.
If you marry me Illl help you.
I will gladly marry you.
But I need to do it myself or I will be cheating
Then Aeson´s son Jason came. He was here to fing a way to stop Pelias. Pelias said that the only way to get Aeson king again is to go and get the Golden Fleece abd bring it back to the castle. Pelias knew that it was an impossible challenge for Jason and that most likely he would not return.
So Jason agreed that he would go and get the Golden Fleece and bring it back to the castle. He gathered a group of Argonauts and began the mission. When they were on the boat they got attacked by a flock of hideous Harpies They fought off the Harpies and continued on their journey.
When Jason was on his way towards the Golden Fleece he came across the kings daughter, Medea. Medea told him that how he had fought off the Dragon-Toothed Army was very impressive and that she would be willing to help him get the Golden Fleece and marry him. Jason said he would love to marry her but that he needed to do the task alone, or it would be considered cheeting.
