The Mountain Men

Lore & Background

In the centuries following the nuclear devastation that rendered the lowlands toxic and hostile, a subset of survivors sought refuge in the higher elevations where the air was cleaner and the terrain offered natural defences. Over generations, this group coalesced into the Mountain Men, forging a society governed by a matriarchal line of authority. Their culture emphasises self-reliance, communal labour, and a deep reverence for the mountain itself as both provider and protector. Unlike the surface clans, whose social structures often revolve around warrior hierarchies and territorial conquest, the Mountain Men's identity is rooted in stewardship of the vertical landscape—terraced growing, mineral extraction, and the careful management of scarce water sources.

Their isolation meant they developed technologies and social norms in parallel with, but distinct from, the grounders. This divergence creates friction whenever contact is forced: the Mountain Men view the surface communities as chaotic and short-sighted, while the grounders see the mountain people as insular and hoarding resources that could sustain more. The matriarchal structure, in which leadership passes through a defined lineage rather than through combat or democratic vote, is a point of particular cultural tension when the main cast, shaped by the more fluid and often violent politics of the 100 and the grounder clans, attempts to negotiate alliances or extract aid.

The Mountain Men's story is ultimately one of a people who chose survival through separation, and who must then reckon with the reality that the world below has not simply vanished. Their arc raises the central question of The 100's later seasons: can isolated communities rebuild trust, or does the weight of generations of separation make cooperation impossible without one side surrendering its identity?

In Their Own Story

The wind up here does not blow; it screams. Clarke pressed her back against the basalt wall and watched the matriarch's guards descend the switchback trail, their boots finding purchase on the lichen-slicked stone with an ease that spoke of a hundred generations of practice. Below, the valley fog swallowed the world she had known—no cities, no ruins, no memory. Just grey and the distant ring of a hammer on iron. The matriarch herself did not speak. She did not need to. She simply held up one weathered hand, palm outward, and the two armed guards at her flank lowered their spears a fraction. An invitation, or a warning. Clarke could not tell the difference, and in the mountains, she was beginning to understand, the difference did not matter. What mattered was whether you stayed, or whether you climbed back down into the poisoned lowlands and pretended the sky still belonged to everyone.

Reader's Guide

The Mountain Men (Skaikru) are a matriarchal faction that established itself in the high-altitude mountain ranges during the long post-war isolation period. Their founding is rooted in the practical necessity of seeking cleaner air and natural defences above the irradiated lowlands, and over generations this practical separation hardened into a distinct cultural identity.

Leadership is vested in a matriarch whose authority is both hereditary and functional—she is expected to embody the community's values of stewardship, patience, and collective survival. Beneath her, a small council of elder women and senior guards administers daily affairs: water allocation, harvest cycles, dispute mediation, and the training of young people in the skills the mountain demands. There is no standing army in the grounder sense; defence is a communal obligation rather than a specialised caste.

Their territory is the vertical landscape itself—terraced slopes, cave systems, high meadows, and the mineral veins that sustain their limited metalwork. They do not claim the valley floor or the lowland forests, and this geographic boundary is both a practical limit and a cultural principle: the mountain is theirs, and what lies below is not their concern.

Relationships with the surface grounder clans are defined by cautious distance. The Mountain Men trade sparingly—minerals, certain medicinal plants, crafted tools—in exchange for goods the altitude cannot produce. They view the grounders' frequent wars and shifting alliances with a mixture of pity and suspicion. When the main cast arrives seeking aid or information, the Mountain Men's response is shaped by their core ideology: they will not abandon self-sufficiency for the sake of a stranger's cause, but they are not hostile. They are, above all, patient.

Across Season 6 the faction does not undergo a dramatic split or dissolution; rather, its arc is one of forced engagement. The arrival of outsiders disrupts a carefully maintained equilibrium, and the matriarch must weigh the risks of openness against the centuries of tradition that built her community. Internal politics surface in the form of younger members who are curious about the world below and older members who insist the mountain is enough. This generational tension, rather than an outright schism, is the faction's most significant internal dynamic.
