Rhaegar Targaryen who is only depicted in the Season 7 marrying
Lyanna Stark in the vision of Brandon Stark was killed by Robert Baratheon. He
was the rightful heir to the throne of the seven kingdoms but he died.
Rhaegar's first wife was Princess
Elia Martell, who was killed with her children. It is also said that she was
raped before she got killed. Rhaegar secretly married Lyanna Stark at a secret
ceremony at the Dorne.
It is now depicted in this
series-Game of Thrones- that Jon Snow is the son of Rhaegar Targaryen and
Lyanna Stark, making him the rightful heir to the iron throne.
Rhaegar is considered as the
most handsome person in the series. It is somewhere stated that Rhaegar never
liked killing people instead he loved to sing. In one episode Ser Jorah the
Andals (Mormont) states that "Rhaegar fought nobly, Rhaegar fought
valiantly, and he died." His real death was caused by the leader of the
Robert's Rebellion, Robert Baratheon, who later seized King's Landing becoming
the King of the Seven Kingdoms. Finally, Robert was successful in throwing 300
long year reigned dynasty from the world.
