Luxerk, a Nobody used as a last resort by the Organization XIII; a backup 13th Seeker of Darkness. When a group of Keyblade wielders attack the Castle that Never Was, he escapes to another world, unknown to both Nobodies and Heartless alike.
I'm just another Brony that decided to chip in his 2 bits in the creative side of the fandom. Let me know what you think of what I put out there and I hope you enjoy. :)
