The Inhumans are a race of altered human beings that were the result of experiments on ancient humans by the extraterrestrial race, the Kree, embedding into their genetic code the potential to transform and acquire superhuman abilities through a process known as Terrigenesis.
Centuries ago, an extraterrestrial race known as the Kree waged a long war with high casualties. In need of more soldiers, one vicious faction among the Kree decided to genetically modify the DNA of other intelligent creatures across various planets, intending to create a warrior/slave caste that they could use to help win the prolonged war. The Kree eventually came to Earth, where they created their own installation and began experimenting on groups of Humans, using their blood, changing their genetic make up, which gave them the latent potential to develop superhuman abilities.
Before the experiments could be completed, another faction of the Kree came to Earth to shut down the project. The Kree eventually left Earth, believing their experiments were unsuccessful. However, the altered genes of the human test subjects were passed on through generations of their descendants. The Kree also left behind the numerous Terrigen Crystals, contained inside devices called the Diviners, which could be used to activate the dormant genetic modifications.
