The Shadow Baby and Damon Blackfire

Both Damon Blackfire and Renly Brathian had Targaryen blood, but without being actual Targaryen. Both were killed by their brother; in both cases, there was some magic rumored to be involved. The Shadow Baby is just a rumor that there was magic involved, just like it was with Blood Raven. Shout out to Joey Townsend for his work on the theme song.
