After the war with the Faomasi, the Argolin were rendered sterile and had their metabolism modified. On the top of their heads, they have small horns covered in nodules. Most of their lives, Argolins have stable metabolism. These nodules fall off as the Argolin ages, with the last nodule singling death. After this, the Argolin rapidly decays. (DW: The Leisure Hive)
The Argolins were brought together by Theron using force and warfare. He then tried to gain more territory and declared war on the Foamasi. The Foamasi bombed Argolis with nuclear weapons, ending the war in twenty minutes and devastated Argolis.
In the wake of the war, the Argolins turned towards recreation, especially with tachyons for regenerative processes. 20 years after the war had ended, they started to develop a method to create new Argolins. They combined the cells of the surviving Argolins and were eventually able to create a a new Argolin, Pangol. (DW: The Leisure Hive)
