The doors shouldn't have anthing identifying sides/bottom/top when seen from inside the battle room. I'd love to see another built from Dragon Army's view, with the enemies gate always being down.

Thanks for this! It does give back the feeling of the book and I really liked the story, the whole saga in fact. I recommend it The doorway is brilliantly done. I could imagine it following into the rest of the station

Oh my... *Faints*
