Secrets and mystery are all that lies in the ancient lands surrounding Somnambula. Ever since the city was buried all those centuries and millennia ago, creatures have ventured across the scorching sands to discover relics and treasure long since lost. Generations of adventurers and archaeologists have trekked and dug through mountains of yellow-brown sand, hounded by the blazing sun and ever scarce water supplies. With the return of the ‘Pillars of Old Equestria’, however, recent information about the ancient world has come to light. Eager to capitalise on the discovery, Daring Do has fore fronted an expedition to uncover an ancient monument, inviting Rainbow Dash to accompany her on this journey of discovery. However, this journey will become quite literal for the prismatic pegasus, taking her to a place both alien and familiar…
