The Forbidden Valley, situated not a great distance from the Lurch Canyon, was a craggy valley found on the desert planet of Pasaana. Within this valley occurred the Aki-Aki Festival of the Ancestors. The Forbidden Valley's rough landscape attracted adventure seekers, while those who gathered art and regional handiwork searched for items they could trade as unusual foreign treasures beyond the planet.
Following a mission to Pasaana that occurred in 21 ABY, Lando Calrissian became captivated by the unassuming character of the indigenous Aki-Aki people, choosing to stay on the world and exist as a hermit within the Forbidden Valley.
