Athamos was married to Nephele, cloud
They had two children Phrixus and Helle
Nephele left her husband because she didn't like that he was mortal
Athamos remarried to Ino who hated Phrixus and Helle
Ino causes a Phamon to hopefully have Phrixus killed
Athamos sent messengers to Delphi for answers but Ino had the messenger intercepted
Right before he could kill them Helle came down and took them away on a Ram with a golden fleece on its back
Helle fell off when they were crossing the Black Sea and drowned
Phrixus sacrificed the Ram and gave the fleece to Aeetes who hung it on an oak tree in a grove sacred to Ares which was guarded by a dragon that never slept
Cretheus was the new king, married to Leda
Leda had two sons Aeson who was the son of Cretheus, and Pelias whose father was Poseidon
Pelias took the throne and put Aeson into prison
Aeson's wife sent her son Jason to be raised by Cheiron
Jason decided to go and claim the throne
When walking there, he came across a river that was in flood and helped a scared woman cross, losing one sandal
As Jason approached the palace Pelias was scared because he heard a prophecy saying beware of the man with one sandal
Pelias says he will only give up the throne if Jason goes on a quest to Colchis to get the golden fleece
