Trikru

Lore & Background

Trikru, the Tree Clan, is one of the twelve Grounder clans that formed after the apocalypse. As the clan of Commander Lexa, it held significant influence within the Grounder coalition. The clan's warriors, led by figures like Indra and Lincoln, were known for their fierce independence and deep connection to the forest. Trikru existed long before Clarke Griffin's arrival and continued to operate as a distinct tribe, not as a multi-group alliance against threats like A.L.I.E. or the Bardo virus.

In Their Own Story

The dust from the mountain still hung heavy in the air when Clarke looked out at the campfire circle. On one side sat Bellamy, his scars fresh from the war; on the other, Octavia, her eyes hard with the weight of command; and between them, a Grounder prisoner who had once tried to kill them all. They were no longer just Sky people or Grounders. The firelight flickered across faces that shared the same fear and the same hope. 'We are Trikru,' Clarke whispered, not as a title, but as a promise. In that moment, the old maps of hatred dissolved, replaced by a new territory where three broken pieces fit together to form something whole.

Reader's Guide

Trikru functioned less as a rigid hierarchy and more as a fluid coalition led by those who could bridge cultural gaps. Clarke Griffin served as the primary unifying figure, often acting as the voice of reason between the impulsive Skaikru warriors and the traditional Grounder leaders like Lexa or later Octavia. Their core belief was that survival required the integration of Ark technology with Grounder resilience. The group's goals shifted from immediate defense against Mount Weather to preventing a total war between the clans, eventually aiming to stop A.L.I.E. Conflicts were frequent, as old prejudices died hard among the members. Skaikru often struggled with the harshness of Grounder justice, while Grounders initially viewed the Sky people as naive invaders. However, shared enemies forced them into alliances that became bonds of blood. The group's greatest strength was its adaptability; they could operate in the high-tech environment of the Ark or the brutal wilderness of Earth. As the series progressed, Trikru members often found themselves leading larger movements, proving that their hybrid identity was the key to saving humanity.

Did You Know?

• Trikru translates to 'Tree Clan' in Trigedasleng, not 'Three People.'
• Lexa was the Commander of the Grounder coalition and the leader of the Trikru clan, not a leader of a post-Mount Weather alliance.
• Trikru existed long before the Ark's arrival, as the clan of Lincoln and Indra.

Origins and Etymology

The Trikru, often referred to as the Tree People or Trigedakru in their native tongue, represent the dominant Grounder clan in eastern North America. Their existence traces back to Callie Cadogan, a visionary leader who escaped the Second Dawn bunker alongside followers after securing the Flame and Nightblood. This exodus was driven by a mission to locate other apocalypse survivors using the limited supply of radiation-curing blood. The very name Trikru holds deep historical significance; it was inspired by an environmentalist organization Callie belonged to before the nuclear disaster known as Tree Crew. Pronounced identically, this connection highlights how pre-apocalypse ideals were preserved and transformed into a new tribal identity. Furthermore, the linguistic foundation of their culture, Trigedasleng, was remarkably crafted by Callie herself when she was merely ten years old. This English-based pidgin language serves as the primary mode of communication for the Grounders, distinguishing them from the Sky People who arrived decades later from space.

Clan Hierarchy and Geography

Within the vast landscape of post-apocalyptic North America, the Trikru stand as the preeminent power among at least twelve distinct Grounder clans. While other tribes like the Ice Nation (Azgeda) or the Boat People (Floukru) occupy specific territories, the Tree People dominate the woods and hold significant influence over regional politics. Their status is often contrasted with groups such as the Mountain Men, who view all surface dwellers as Outsiders, or the Sky People, who initially perceive Grounders as barbaric savages. The Trikru's dominance is not merely territorial but cultural, serving as a primary antagonist force in early conflicts before relations began to shift under the leadership of Commander Lexa. Other clans mentioned include the Glowing Forest (Trishanakru), Rock Line (Boudalankru), and the Desert Clan (Sankru), each with unique names derived from their environments. Despite these divisions, all Grounders share a common biological heritage: an enhanced tolerance to nuclear radiation that allowed them to survive on Earth while others perished or remained hidden in bunkers.

Cultural Identity and Language

The cultural fabric of the Trikru is woven tightly with Trigedasleng, a language that serves as both a practical tool for survival and a marker of identity separate from the English-speaking Sky People. Created by Callie Cadogan at a young age, this pidgin dialect bridges the gap between pre-apocalypse English and the harsh realities of life on Earth. While many Grounders possess knowledge of standard English, Trigedasleng remains the heart of their society, reinforcing their distinct separation from the Ark survivors who descended ninety-seven years after the nuclear event. The language reflects a community that has evolved independently for nearly a century, developing its own traditions and social structures away from the technological remnants of the old world. This linguistic barrier initially fueled hostility between the Sky People and Grounders, as mistranslations and cultural misunderstandings exacerbated tensions. However, over time, this shared tongue became a vehicle for diplomacy, allowing figures like Lexa to negotiate peace and slowly dismantle the negative stereotypes held by both sides regarding one another's intentions and capabilities.

Founding Mythology and Leadership

The history of the Trikru is inextricably linked to the legacy of Callie Cadogan, whose actions following her departure from the Second Dawn bunker laid the groundwork for Grounder civilization. By taking the Flame and Nightblood, she initiated a journey to find other survivors, effectively founding the clans that would eventually populate the Earth's surface. The narrative reveals that Callie was not just a leader but a symbol of hope who intended to use the limited Nightblood supply to save up to two thousand additional people. This foundational myth underscores the Trikru's role as protectors and seekers of humanity amidst the ruins of the nuclear apocalypse. Their leadership structure, exemplified by figures like Lexa, evolved from these early days of survival and exploration. The discovery of Azgeda symbols in bunkers suggests a complex history involving other tribes and mysterious artifacts like Earth's Anomaly Stone, hinting at deeper alliances or conflicts that shaped the Grounder world long before the Sky People returned to the planet.
