how do dragons fly? (Spoilers all books to end DH)

[assasin]

I'd seriously disagree with you about "as close to natural as possible". Dragons are too big to fly naturally. Full stop. I know of no animal in history that size that could fly. There is no indication of the air preasure being different to earth. The gravity is the same. You get the idea.

Also, dragons are pretty much immortal [not counting starvation, disease, injury, etc. Just age.]. I know of no animal that is immortal. But i know in the realm that skill users could age a lot slower. Through the use of MAGIC.

Not to mention the dragons ability to absorb memories. The ansestral memory. menatl communication. You get the idea.

The very nature of dragons is magic .If there was no magic they most likely would be dead. I think the reason that there is acid instead of fire is that magic in the realm sffects living beings instead of haveing elemental effects [ie no fireballs for skill users or lightning bolts for old bloods. though wit bonds and skill healing is possible]
