Gruuthar of the Northern Mountains challenged King Blackthorn to a game of chess. Unsurprisingly, Gruuthar lost. Being a notoriously sore loser, he vowed revenge-  or at least, a rematch. At this time, the Britannia postal system was in chaos, as Minax had taken over the delivery routes. So, Gruuthar's request for a rematch never reached the king. Now, he sulks up and down the mountains, vowing revenge... What can you do? Some people are really petty. Come and help us repel his invading forces, grow your death robe collection, and have fun!

This Royal Britannian Guard mission has the codename "Find My Heart." To attend, go through the moongate inside the Britain Counselor Hall.
