Melisandre often says there is power in King's blood, but she doesn't mean just any king. So whose blood is more "royal," really? It's all about perception.īut mostly though the bolded part isn't really supported in the text. Hell, the Starks, Lannisters, Arryns and so on were kings for thousands of years before the Targaryens ever set foot on Westeros. To base this question on the assumption that only Targaryen blood is "kingly" is a major misstep, in my opinion. Robert's blood is important not because it's Targaryen blood, but because Robert was, you know, a king. I think this is a huge stretch and an assumption and doesn't mesh with what we see in the books - namely that, for instance, burning Mance and his son "so that both die kings" is considered acceptable (even though Melisandre burns a fake), and neither of them have Targaryen blood.

The question is, why is Targaryen blood divine in the religion of the fire god? Does this power somehow relate to the ongoing "Song of Ice and Fire"? Targaryen blood is powerful, but why? Is there anything that could tie the Targaryens to the god Rh'llor?

The Baratheons are an offshoot of house Targaryen, which explains why Melisandre sees Stannis as Azor Ahai, and also why Melisandre seeks the blood of Baratheons in performing rituals. Only those with lineal ties to the Targaryens are considered to have King's blood. Not only in terms of who has the best claim to the throne, but also in terms of the magic of Rh'llor. Lineage is an important aspect in ASoIaF.
