The King of Gnawnia has called brave mouse hunters to his kingdom to fight the mice that are destroying his lands. It is he that pays rewards to hunters. He also has the power to increase the rank of a hunter. The kings name has not been revealed though several contests have been offered to determine his name.
The king knows how bad the mouse problem is in Gnawnia from personal experience. On September 10 his crown was recovered by hunter, Amy White. The crown had been stolen by a Master Burglar Mouse.
