The Cello Forest チェロ森, cheromori?) is a small forest, which also serves as the path that connects Frontier Village Karulu with Airport City Nemo, and in essence, it's the main road that goes from the village to the rest of the Wings of Horus. The forest itself takes its name from one of Ar Ciel's moons: the Cello Moon, similarly how the Viola Forest takes its name from the Viola Moon.
