Grounders/Trikru

The Woods Clan, also known as People of the Woods, Trigedakru, Trikru, and Tree People, are a Grounder Clan that inhabit the expanse of woodlands around the area in which the dropship landed. Their borders also extend to the location which was once Washington, D.C. but is now known as Tondc. Their largest city and capital is Polis. and is where the Commander resides.

The Woods Clan maintain a hostile relationship toward the Reapers, Mountain Men, and Sky People. When the Delinquents first landed in their territory and burned a village to the ground, they retaliated and a conflict broke out. The Sky People, however, continued to seek peace with them. At first, Lexa, the Commander of the 12 Clans, was willing to extend peace to the Sky People provided that the Sky People leave their territory. Eventually, the Sky People and the Grounders form an alliance and agree to work together to free their people from Mount Weather. After the Commander forms an alliance with the Mountain Men in exchange for her people imprisoned within Mount Weather, it leaves the Delinquents at the mercy of the Mountain Men and jeopardizes the alliance between the Sky People and the Grounders.

Society
The Woods Clan are a group of Grounders that came together after the Armageddon 97 years prior. Most children begin to learn from a young age how to be warriors and are taught English, weapon skills, and their people's customs.

After the first kill is made, the member is honored by receiving a mark on their right shoulder blade. This mark signifies that the person is now a warrior and has killed. Oftentimes these markings look like welts on the skin as if burned.

If a child is born with a mutation, they are cast out and abandoned to erase the stain from the bloodline.

Language
Woods Clan warriors are known to speak their native language, Trigedasleng and American English (Gonasleng). They are referred to as the "Trikru" in Trigedasleng.

Trigedasleng is a universal language, meaning most if not all Grounder Clans know this language. Only the Warriors speak English, which makes them bilingual.

In Season Two, Lincoln teaches Octavia some of this language to help her blend in as a Grounder. With Lincoln, from The Woods Clan, going to Luna's Clan, it can be assumed that all Grounder Clans speak this language.
