During the years when Daventry went into decline due to the loss of the three treasures, the Raging River flowed through the wilds of the kingdom south of Castle Daventry, where it passed the Mushroom Isle (location of the Land of the Leprechauns) in the bend in the river known as the Dangerous River and then split into two tributaries which passed around the Island of the Gnome. The river was quite treacherous earning it the additional name the River Fools.
