The 100

Origin: Grounders who were captured by the Mountain Men (the scientists inside Mount Weather) and horrifically altered.

Technology & Lifestyle: Sub-human and feral. They do not build societies, wear proper armor, or speak. They live in underground tunnels and serve as a terror force for Mount Weather.

Biology: They are the product of chemical torture. Mount Weather injected them with a highly addictive drug called The Red Thorne, transforming them into cannibalistic, rage-fueled monsters who experience zero pain.

Mindset: Purely animalistic, driven entirely by withdrawal and the urge to feed on human flesh. They hunt Grounders and Skaikru to deliver them to Mount Weather in exchange for more drugs.

Origin: Descendants of humans who survived the nuclear bombs on Earth's surface, largely descended from a pre-apocalypse doomsday cult called The Second Dawn.

Technology & Lifestyle: Primitive and tribal. They live in a feudal society divided into 12 clans. They banned guns (due to a truce with Mount Weather) and fight using swords, spears, bows, and martial arts.

Biology: Naturally selected survivors. Over generations, their bodies adapted to tolerate Earth's radiation, though a rare genetic mutation yields Nightblood (black blood), which grants total radiation immunity.

Mindset: Driven by a warrior culture, spiritual mysticism surrounding the "Flame" (an AI chip embedded in their commanders), and the harsh law of "Lex Talionis" (blood must have blood).

Origin: Survivors who escaped into space and lived aboard The Ark space station for 97 years.

Technology & Lifestyle: Highly advanced. They utilize firearms, modern surgery, computers, and engineering. They wear manufactured clothes and uniforms.

Biology: They possess engineered radiation resistance because their ancestors genetically adapted to solar radiation in space. This allows them to walk Earth's surface safely.

Mindset: Focused on rebuilding democratic civilization, law, and order, but highly naive about planetary survival when they first land.

Skaikru (Sky People) is the 13th Clan of the Grounder Coalition. They are the descendants of the humans who survived the first nuclear apocalypse by living aboard "The Ark"—a massive, interconnected space station orbiting Earth. Unlike the Grounders, who adapted to a primitive, tribal lifestyle, Skaikru retained advanced technology, modern medicine, firearms, and formal scientific knowledge.

Culture and Society
The Ark Structure: Originally governed by an elected Chancellor and a strict, authoritarian Council. Due to critically failing life support systems, any adult crime was punishable by execution ("floating" into space), and families were limited to one child.

The Delinquents: The initial 100 juvenile prisoners sent to Earth as test subjects to see if the planet was habitable. They formed the cultural bridge (and conflict) with the Grounders.

Identity Shift: They transitioned from highly organized, law-abiding space-dwellers into hardened planetary survivors. Over time, they abandoned their strict "Ark" titles to match the brutal realities of Earth.
