The Bloodstone Wars are raging in the Forgotten Realm of Faerûn to the east of Blackmoor.
An invading force led by the villian known only as The Witch King has been struggling to gain control of a large expanse of terrioty within the Bloodstone Pass. This territory is named Bloodstone after a precious ruby mined throughout the region. As the conflict escalated, the Realm of Blackmoor was at risk. Thus, King Henry raised an army and engaged in battle along with the forces of Men, Dwarves, and Elves fighting in the Bloodstone lands.
If the Witch-King is victorious then his next target could very well be Blackmoor, and all of the Flanaess.
