Southern Kalimdor (aka South KalimdorLoM 49) is the southernmost subcontinent/territory on Kalimdor, south of Central Kalimdor.LoM 3, 49 Southern Kalimdor is by far the wildest area of the continent. Much of its lands are uncharted, and there are few settlements larger than small towns. Ancient ruins dating back to the Sundering — and earlier — dot the landscape. The terrain varies from thick forests and jungles to vast desert wastelands or bleak salt flats. The creatures that dwell there are vicious and deadly. One should not venture forth into the south without plenty of supplies and good, strong weapons at his side. There are five major regions in southern Kalimdor: Feralas, Thousand Needles, Tanaris, Un'Goro Crater, and Silithus. The last two are the hardest to reach, and are also uncivilized.LoM 49, 50
Note: Southern Kalimdor is often described as "southern Kalimdor".
