So yeah. I am a BIG Kingdom Hearts fan. This work has a lot of back story to it...it is part of a theory I have that is during the final battle(s); all of Sora's friends lose their heart; but more like how Kairi was in KH1. So Sora is fighting Master Xehanort and his Keyblade breaks. He remembers what he said about his freinds being his power and how at that moment he felt it to be untrue. Then his friends hearts, as well as those he will save from their Birth By Sleep come to him and create this Keyblade. Sora defeats (read: weaken) Xehanort and the hearts return to his friends. All is good until Xehanort strikes them. Then Sora gains the X-blade.
I first drew it out and coloured in most of it. Then I scanned it and added the background and fixed up the blade.
I fashoned the Keyblade to look like the Kingdom Key. I did this because it is of simple design and it also ties into my theroy of Sora's homeworld being Kingdom Hearts.
I made it have a dark/light motif because of the darkness and light in peoples' hearts. I made one part blue because a) Sora's eyes are blue and b) that is the colour of the game's title logo
