Actually, it is neither about Corum nor Hawkmoon. It is about John Daker, whose most well-known and important incarnation is Erekose. The reason why there are references to Corum, Elric, Hawkmoon and their actions and characteristics is that John Daker is the only Champion who is able to remember all of his incarnations, past and future, so he is also Elric, Corum and Hawkmoon. Apart from the obvious referenced in the lyrics, the title of the song also indicates that. John Daker is eternally doomed to bear the memories of all his incarnations.
