Soldiers and Spies- Remnants of the regime of the late Fuhrer Bradly are at risk of falling into dangerous hands, unless the Hound of Amestris is able to prevent potential disaster.

Siblings in Arms- Leon is called to meet the new leader of Nightshade, whom he has not seen since leaving the group two years prior.

The Past 10 Years

At the start of Fullmetal Alchemist: Heart of Sin, roughly ten years have passed since the end of Fullmetal Alchemist: Brotherhood. Obviously, with Amestris having been left facing many serious changes at the end of the canon series, the ten years prior to the start of the Fanon Canon are also filled with changes, not just in Amestris, but the world of Fullmetal Alcehmist.
