Post-LOTR AU! King Fili sends his brother on a mission to deliver much needed gold into the hands of envoys from war-ravaged Rohan. But while Kili is away from the lands of Erebor, vengeful enemies strike at the very heart of Erebor's King and Fili makes a sacrifice. Is there anyone who can save Fili before it's too late?
