Mass Effect 2 & Mass Effect 3
Vecchio is a moderately-sized terrestrial world with a thin, hot atmosphere of carbon dioxide and nitrogen. Initial surveys found trace amounts of iridium, but little else of interest in the silicate desert sands that cover much of the surface of the planet.
On a recent tour, the Alliance surveyor ship Kupe discovered a group of partial graves hidden in the equatorial mountain ranges. The ancient skeletons in the burial sites are obviously humanoid but incomplete and poorly preserved, which has made them difficult to identify. Fragments of primitive ceramic grave goods were also found nearby. This raises further questions about who once traveled to this inhospitable planet since the closet garden world, Volturno, has no intelligent life. Human universities are planning further archeological investigations.
