Skaikru

Skaikru is a fictional political and cultural faction in the television series The 100. The term refers to the descendants of the Ark who descend to Earth after a nuclear apocalypse. Grounders refer to them as Skaikru, or the Sky People, reflecting their origin in space rather than on the planet. The Skaikru form the core of the Ark survivors who establish a society on the surface of Earth.

Origins and settlement: After the Ark’s ships bring humanity's remnants to space, a group of 100 delinquents is sent to evaluate Earth’s habitability. Upon reaching the surface, they unite as Skaikru and establish a foothold on the ground. Their main settlement on Earth becomes Arkadia, a fortified base built on the remains of Mount Weather’s facilities. Governance within Skaikru combines councils, leadership by elected or consensus figures, and a strong emphasis on survival and rebuilding. Clarke Griffin emerges as a prominent leader among the younger generation and a key representative in dealings with Grounder clans and other factions.

Culture and relations: Skaikru interacts with various Grounder clans, negotiating treaties, forming alliances, and sometimes engaging in conflict. They rely on salvage and adaptation of Ark-era technology, while also developing farming, medicine, and military capabilities. Over time, Skaikru becomes one of the principal factions on Earth, navigating a complex landscape that includes tension with Grounders, remnants of Mount Weather, and other powers striving for influence.

Notable members: Clarke Griffin, Bellamy Blake, Monty Green, Jasper Jordan, Raven Reyes, and Octavia Blake are among the best-known Skaikru figures. The group’s fortunes drive much of the series’ political and social dynamics.
