a drawing of Kindom Hearts for a contest, that I won, 2 years ago! :3 It represent Sora, along Lightning, discovering a keyhole in the center of Eden.
Then Sora get Lightning's keyblade: Thunder in bloom. It has the same design as Odin's blade, and in the center there is her crystal roses.
This blade provide Red spark of electricity, and let petal roses flow behind it!
