In southern Africa there are ruins from a mysterious unknown race. There is the most vast stone age (therefore very ancient) built settlement, going from South Africa, Zimbabwe, Botswana, and parts of Mozambique. The indigenous bushmen of the region are disputably the descendants of the ancient race who created it. The origins, however, are uncertain. The biggest of the structures is a tower like fortress and various other buildings called the ruins of Great Zimbabwe. There are few artifacts besides the structures found, however one famous artifact is a stylised eagle carved out of soapstone. Modern Zimbabwean sculptors create pieces in the same style inspired by the mystery of the Ancients. There is a growing popularity amongst some scientists for the theory that southern Africa is the true cradle of mankind.
In South America (Peru, Bolivia, Mexico), there is rumoured and told by the local people that there is a network of subterranean tunnels running possibly parallelesque along the Andes, connecting the ancient cities. It may have been built by giants (white men with beards and/or large heads and eyes) who settled in ancient time and were driven underground, or "ant people" that have apparently rescued the Hopi Indians time and again. Treasure hunters, Atlantis and Lemurian (Mu) theorists (believing there is a network that originated from the holy Atlantis), intrepid explorers, cavers, and mystics have searched for these places. Granted, it is very difficult terrain. On the rare occasion, one of them or wayward travellers, usually accidentally, will return with strange stories (of another world). Generally, anyone who spends a long spell in the South Americas have a few strange tales!
