Whoops, I thought I had responded to this comment hours ago. I iz brain ded.
When this fic started nibbling, I knew it was going to be manga-verse and post-apocalyptic. To work with the idea I had in mind and still keep some of the canon in mind, it had to be the final Ancient Evil/Zork battle.
From there, we'll have to see what happens. I have faint ideas, but nothing definite.
