Pairing/Characters: Roy Mustang, Scar. No pairings.
Warnings: Probably some non-explicit nudity at some point or another--Ishbalan mores on nudity don't line up perfectly with western ideas. Likely to be some supporting-OC death. Lots of culture-building. Mild language and some violence.
Summary: Post-manga AU. Roy Mustang can't bear to use Dr. Marcoh's Philosopher's Stone, and Jean Havoc won't take it unless Roy does. They don't dare leave the Stone unused, so they present the Stone to Scar, who's been recuperating from the events of the Promised Day at the Armstrong estate. Scar decides to take the Stone to the Ishbalan Elders--and Roy goes with him as an emissary of Amestris. Instead of going into southern Ishbal, however, Scar takes Roy north and east, to the ruined city of Xerxes. Heartache, frustration and some threats to Roy's life ensue while he tries to negotiate an end to the fighting and some form of reparations, as well as delivering the Stone full of Ishbalan dead to the Elders. Meanwhile, Scar is facing the consequences of his own past. He was once a warrior-priest, bound by an oath made before his God and his people. Breaking that oath to go on his solitary rampage of vengeance carries a stiff penalty. Somehow, two of the least likely messengers Ishvarra could have picked must find a way to not only work together but also to save both their people and themselves.
