In the Burning Wall there are these creatures straight out of XII called Mirrorknights. I forget if that was their name in XI as well.
I played the SH*T out of FFXII: International Zodiac Job System, so when I saw those while randomly exploring and trying to rank up in my GC, I was very happy.
Playing the translated IZJS emulated at 2x resolution on my PC was one of the best gaming experiences I've ever had. It makes me wish so much that SE will release an HD version of that gem of a game.
