Genetic Council

Unregulated Terrigenesis
The Inhumans were a gentically-modified offshoot of humanity who were created by the Kree centuries ago and lived in isolation. When Randac, the leader of the Inhumans, discovered that exposure to the Terrigen Mist caused their race to gain fantastic powers, the Inhumans began to indiscriminately expose themselves to Terrigenesis.

Creation
This eventually led to many monstrosities being created. As such, the Genetic Council was formed as a means of enforcing selective breeding practices among the Inhumans to ensure that their people maintained useful transformations. Since its creation from Randac's era, the Genetic Council also served as the government of Attilan and the major legislative, judicial, and executive body.

The Genetic Council operates separate from the Inhuman monarchy, their authority eventually superseding the authority of the crowned king. As the majority of the Council are elders of the Inhuman race and are often left in charge during periods in which the royal family was absent.
