I really have to read the book soon, I'll buy the Seamus Heaney Edition the next time I go to the bookstore, probably on Monday.
What if SG Beowulf has a royal ancestry, but for some reason he was lost or even abandoned at birth? Maybe he was forced to live a life of poverty, and discovering and claiming his heritage may be part of his climb to the top! Maybe his family believes that his place on the throne must be earned and his reason for fighting is to prove himself as the rightful king! Sort of like Disney Hercules!
I don't think Alex Ahad will actually go in that direction for his story, but it's cool to imagine.
