Grounders/Trikru

The Woods Clan, otherwise known as People of the Woods, Trigedakru, Trikru and Tree People, are a group of Grounders 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 now it is known as Tondc

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

The Woods Clan maintain a hostile relationship towards Reapers, Mountain Men, and the Sky People. After the rest of the Ark survivors landed, they sought peace with the Trigedakru. This was impeded by the massacre at TonDC; however, this was quickly resolved through the death of Finn Collins, bringing tentative peace and alliance between the two groups.

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.. These markings are self-made. 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.

The Woods Clan will fight with swords, daggers, spears, bows, fists, and have even been known to fight with their teeth. Many members are skilled in hand-to-hand combat.

Members of The Woods Clan have often been shown in some type of armor. Most of the time their armor is made out of a variety of materials such as: bone, leather, cloth, and animal furs. They often wear masks or helmets made out of: bone, wood, and a variety of other unknown materials. Many have war paint on their face and body. Many members appear to have tattoos on their face and/or body. Little else is known about them. It is possible these tattoos indicate a status or rank in their society. They could also just be decoration.

The Woods Clan are known for being fearless and do not show mercy to their enemies. However, they have been shown to want peace with their enemies, specifically the Sky People. The Woods Clan are willing to extend peace to the Sky People provided that the Sky People leave their territory.

The Woods Clan Commander is not chosen or voted for. When the commander dies, their soul passes on to the next person to choose the next commander.

Language
The Woods Clan have their own language. Trigedasleng is a universal language, meaning most if not all Grounder Clans know this language.

Some Grounders, particularly warriors and scouts, are known to speak the common language, English. This makes many Grounders bilingual.
