Jasper's Faction

Lore & Background

In the world of The 100, the Grounders are not one people but a patchwork of tribes—City of Light, Mountain Tribe, Skaari, and others—each with its own customs, grudges, and survival logic. The Mountain Tribe, dwelling in the rugged highlands, is defined by a warrior ethos that prizes strength, self-reliance, and a deep suspicion of outsiders. Into this world steps Jasper Morehouse, a young Grounder whose defining trait is not his blade but his loyalty. He attaches himself to Lincoln, a Skywalker who has been adopted into Mountain Tribe life, and becomes his shadow, his second, his friend in a culture that would normally view a Skyborn with contempt.

Jasper's small circle exists in the tension between tribal duty and personal bond. The Mountain Tribe's hierarchy is martial and pragmatic; a young warrior does not command a faction by title. Yet Jasper's devotion to Lincoln earns him a kind of informal authority among the men who respect that he would die for his friend without hesitation. This makes him a living contradiction within Grounder society: a warrior whose greatest strength is not his killing but his caring.

As Season 4 escalates—facing the Skaari, the Reapers, and the slow unraveling of Grounder unity—Jasper's faction becomes a symbol of what is lost when the larger tribal structures fracture. His loyalty is the thread that holds Lincoln's dual identity together, and its eventual testing is one of the season's most emotionally devastating arcs.

In Their Own Story

The wind off the ridgeline tasted of iron and pine resin. Jasper crouched behind a boulder the size of a small hut, his breath fogging in the cold, and watched the valley below where the Skaari ships sat like dead birds. Beside him, two Mountain Men sharpened their weapons in silence, the rasp of stone on steel the only sound. He did not look at them. He looked at the tree line where Lincoln would be, counting seconds, waiting for the signal.

"You sure about this?" one of the men muttered, not looking up from his blade.

Jasper's jaw tightened. He did not answer. He never needed to. The answer was written in the way he held his spear, in the way his eyes never left that stretch of forest. If Lincoln was there, Jasper was there. If Lincoln fell, Jasper fell with him. It was not a vow spoken aloud. It was simply the shape of the man he was.

The sky shifted. A shadow passed over the valley. And Jasper was already moving, already running, already choosing the only direction that mattered.

Reader's Guide

Jasper's Faction is best understood as an informal loyalty cluster within the Mountain Tribe rather than a codified political entity. It has no founding charter, no elected council, and no defined territory beyond whatever ground Jasper and his small band of warriors occupy at any given moment. Its 'leadership' is singular: Jasper Morehouse, a young Grounder warrior whose authority derives entirely from personal reputation and his unshakable bond with Lincoln.

The Mountain Tribe itself operates on a martial hierarchy where strength and combat achievement determine status. Jasper does not rise through that system in a conventional sense; his standing is earned through the loyalty he demonstrates and the protection he offers. This makes his 'faction' fragile in a political sense—there is no institutional backing, no territory to defend, no succession plan. It exists only as long as the personal bonds that form it remain intact.

Relationships with other groups are defined by proximity and conflict. The Mountain Tribe is wary of the City of Light Grounders and openly hostile toward the Skaari. Jasper's circle inherits these tensions but adds a personal layer: his loyalty to Lincoln, a Skywalker, places him in a socially ambiguous position within Grounder culture. This internal tension—tribal duty versus personal devotion—is the central political dynamic of his small group.

Across Season 4, the faction does not so much evolve as it is tested and ultimately consumed by the larger conflicts. There is no split, no formal dissolution; there is simply the moment when the bonds that held it together are stretched beyond their breaking point, and the faction dissolves into the broader tragedy of the season.

Did You Know?

• Jasper Morehouse is one of the few Grounder characters whose primary motivation throughout his screen time is personal loyalty to a single friend rather than tribal politics or survival strategy.
• His bond with Lincoln is notable because it crosses the Skywalker-Grounder divide at a time when that boundary is the single most dangerous social line in the post-apocalyptic world.
• The Mountain Tribe, Jasper's parent faction, is visually and culturally distinct from the City of Light Grounders, emphasizing rugged terrain, martial discipline, and a more insular worldview.
• Jasper's role as Lincoln's bodyguard and companion gives him a narrative function that bridges the Skyworld and Grounder storylines, making him a connective character between the show's two major cultural spheres.
