Well...thank you to A Pierrot's Aria for setting this up! (Sorry I put it in the wrong place!) My fic is called the Elemental Chess Trilogy. It starts roughly three years after the end of FMA, and ends almost four years later. Very spoiler-laden. Because I'm a colossal nerd, it has its own page at TV Tropes, which you can visit here:
The links to the three story parts are on that page and also in my signature, and the folks over in the Royai thread have been more than generous in their praise of the trilogy. Thank you all.
