In a densely-forested part of the territory, and near a large Twoleg Thunderpath, is Thunderbird Falls. A pair of waterfalls rush down from a short cliff-face and into a small pond that houses fish, frogs, and salamanders. Behind the falls lies a cave, concealed by hanging ivy and covered in layers of thick moss. Stalactites displaying their own layers of vegetation hang down from the ceiling, and drip water into tiny pools beneath, creating a constant sound akin to rainfall. The ground is soft and holds onto pawprints.
As one ventures further in, the rock walls grow narrower, until the only thing that's accessible is a thin tunnel made of a strange material that extends out to the surface on the other side of the Thunderpath. Bats sometimes seek shelter in the cave, and crayfish and other tiny fish can be found within the inner pools.
A far wall at the back stands as a living record of honorable past and present high ranks and hornets from the time of the caves discovery.
