I think it is best if Danny wouldn't be a Skyer, since it really does go against the lore of skyers. Skyers are people who are literally built from birth to use and handle Sakra, they literally have their bodies and immune system be weaker and completely forgo the other two, possibly three (I am not sure if Seps can use mana, probably not but maybe.) other forms of magic. I feel like a Skyer's brain would literally shut it self down over snapping over pressures since it is built to handle Sakra and would have some form of safety valve that would auto-correct itself over taking bodily harm. It just does not make any sense to me that a body built from the ground up to handle a certain type of magic wouldn't have some kind of safety against that magic. Shamans obvoiusly have their contract with nature that I am pretty sure includes "Don't kill me Mother Nature please", but I think that Monks and Skyers would have some biological safety, I am not saying that they don't get blacklashes, it is just there bodies handles them so they are not as bad.
