Anyway, now I've maybe calmed down a tiny bit... (Although calming down isn't very possible for me in the presence of this amazingness)
This is utterly wonderful. <3 Night shadow looks amazing, and although it isn't exactly correct her mane looks stunning, and doing it correctly is the biggest pain in the freaking BUTT that I'm ignoring that because I honestly couldn't expect you to know and it looks amazing anyway and it's utterly in your style. <3
And yes, Night Shadow must be doing air magic. From the expression on her face I'd say she's probably blasting a dark one away from her, probably into something hard and maybe spikey like jagged rocks. Honestly, Night Shadow really hates dark ones.
Haha the moment I came on dA the day you posted this thing I just couldn't contain my excitement I'm amazed I didn't blow up my house xD. Honestly, this is wonderful. <3 And I honestly don't mind the kazzen mane, it looks cool! Not sure Night Shadow thought much of the kazzen mane though... xD But she's always harsher than she actually is, if you have any idea what that means. Anyway, don't take Night Shadow's opinion of the kazzen mane to heart will ya? lol
Dark ones? They are the evil ones. Literally, just that. They are evil. Anyone that is evil (And as night will tell you, some that aren't evil also get called this, but only when others think they are evil.) is called a dark one by everyone including the dark ones themselves. Dark ones tend to be black/patchily black and have magic of the darkness element as well as any other magic - in fact when she was turned Night gained the ability to use dark magic and the black in her coat, actually she was fully black as a dark one, and when she turned back turned the colouration she is now and retained the dark magic. That doesn't always happen though, and in fact to be evil you need not have any dark magic at all and you won't get any black without dark magic... The darkness magic just activates the black pigmentation in the hairs in their coat they can't have black fur without being capable of controlling that element... WOW I wandered a bit there! xD I could go on and on about Kesi and the equines, longer even than I could about the elves. (Actually, a lot longer. The elves and Arcadia probably come across as much more developed than they are. xD)
