Talk:Invisible Air

is there any origin of invisible air? i mean, excalibur and avalon has their origin as the sword and final resting place of king arthur. how about the invisible air? is it a form of protection or magic that protects or relates to king arthur? as its title said, "bounded field of the wind king", is king arthur has connection to the elementals of the wind? i'm just curious, please don't be mad at me.
