In Game of Thrones we see that Daenarys can't be burned by flames, would this ability have extended to the rest of the members of House Targaryen?
The reason I ask is that, during the episode where the Night's Watch has a funeral for Aemon, we see that they have him resting on a funeral pyre which they then set alight. The custom would make perfect sense for anyone else, but seeing as he's a member of House Targaryen, it seems like this would have been a fruitless endeavour because it wouldn't actually burn him.
Maybe they'd only have this ability whilst alive though? Is there any mention of this being a trait for Targaryens anywhere in the books? I'm only nearing the end of the first book in the series but I've been keeping up with the show.
