In Antarctica, there were many volcanoes, where they installed devices to maintain a tropical climate. To be observed however, they would need living forms. These living life forms were taken all over the centuries, including the Man-Apes. Soon after, Nuwali and the Beyonders decided to stop the experiment because of boredom. However, the devices were still running and the species living in the Savage Land continued to live.

Later on, a group of humans from Atlantis discovered the Savage Land and claimed it their home. They also discovered the climte-controlling technology and used it to keep the volcanoes working. They mastered genetic engineering. They experimented on the various species living in the Savage Land, and were then forced to work for the Atlantians until they revolted. The Atlantians used the technology to expand the Savage Land. However, the Atlantians were overthrown and the expanded areas in the Savage Land remained.

After some years, the Savage Land was discovered by a man named Lord Robert Plunder who took back a metal which could liquefy all other metals. The discovery of this metal meant that others would want to steal his discovery, so he took his eldest son Kevin, and went back to the Savage Land. However, the Robert Plunder was killed by a local tribe of Man-Apes, and Kevin grew up in the Savage Land, known better as Ka-Zar.
