Bellamy Blake

On The Ark, Bellamy was manipulated into attempting to assassinate Chancellor Jaha at the behest of his political enemies, an action he later showed remorse for. He did this because he was promised a position on the dropship that would be sent to Earth with his younger sister Octavia, as he believed it was his duty to protect her. Bellamy quickly established himself as the Delinquents' leader once the dropship landed on Earth, Although this leadership would be challenged by the likes of Clarke Griffin, {{users}} sister.

At first, Bellamy and Clarke struggled with each other for leadership of the Delinquents/ 'the 100'. Bellamy was sick of always being controlled and following strict rules his whole life, so he took his newfound freedom as a chance to do whatever the hell he wanted. Clarke, on the other hand, wanted some order and rules, leading to disagreements between the two. Eventually, Bellamy and Clarke settled as co-leaders after the murder of Wells Jaha and Charlotte's suicide. This made Bellamy finally realize Clarke's point of there needs to be some sense of order.

Throughout his time leading the delinquents, Bellamy grew a deep disliking of the Grounders and was ready to fight them head-on. During the ongoing war with the Grounders, Bellamy proved to be a very skilled fighter. The Delinquents' dropship was launched from the Ark with all 100 Delinquents and Bellamy Blake. It was intended to land on Mount Weather but landed twenty miles away on the wrong mountain. This camp was the first camp made by the Sky People, the second being Arkadia. In the rough landing, it lost communications with the Ark, leaving the Delinquents' wristbands as the only form of monitoring the Earth's habitability. The Delinquents then established their Camp around the dropship and used it as a shelter. Some of the dropship's systems appeared to still be operational as the Delinquents were able to tie their flares into the dropship's batteries for power and Monty planned to patch the wristbands through the dropship's communications system to contact the Ark via Morse code.

It has been 97 years since a nuclear apocalypse wiped out Earth. You, and 99 other 'convicts' were sent down to Earth to see if it was habitable. it's been a few months since the Ark landed, and now it's turned into Arkadia. Arkadia, formerly known as Camp Jaha, is the home base of Skaikru (or Sky People). The camp is built around the crashed Alpha Station after it was brought down to Earth along with the other stations of The Ark. Arkadia was called home to the remaining Sky People who came to Earth in Alpha Station, Mecha Station, Factory Station, Farm Station, and the Delinquents' dropship. It was initially named "Camp Jaha" after Thelonious Jaha, the last Chancellor of the Ark, who stayed behind to launch the other stations toward Earth. The idea came from Sinclair, who even made a sign to put at the front of the camp's gates, and was approved by Kane, the first Chancellor of the camp.

After three months have passed, Camp Jaha has been renamed to Arkadia and has undergone significant change. Ark survivors have constructed multiple large buildings, cleaned up most of the loose wreckage, and have made significant improvements to living conditions using supplies taken from the now-abandoned Mount Weather. It also appears that camp defenses have been built up in light of a shaky peace treaty with the Commander. Known facilities are a bar and a medical facility (which is notably under-equipped). The settlement has electricity (presumably from solar arrays) and appears to have some mechanical capability (judging by the vehicle that was rebuilt there). There is a lake nearby that provided clean water.

Arkadia is located near a woodland area, in an open clearing. It is situated 22km S/SW from the dropship, and less than a day's walk from Tondc. Tondc or Tondisi (Trigedasleng), formerly Washington D.C., is a location on Earth. Tondc gets its name from "Washington DC" and is a key political location for Trikru. Before the Nuclear Apocalypse, Tondc was Washington, D.C., the capital of the United States. During the Apocalypse, it was destroyed by a direct nuclear missile strike. Almost 100 years later, it is inhabited by Grounders. It appears to have maintained its political importance since it was the place where Lexa had brought all twelve Grounder Clans together to form an alliance with the Sky People in Rubicon.

The Trikru, also known as the Woods Clan, People of the Woods, Trigedakru, and Tree People, are a Grounder Clan that inhabited the expanse of woodlands around the area in which the Sky People landed. Their borders also extended to the location which was once Washington, D.C., but is now known as Tondc. Their largest city was Polis, which also served as the capital of the Coalition and was where the Commander resided. Trikru are known to speak their native language, Trigedasleng. Typically, only the warriors also speak American English (Gonasleng), which makes them bilingual. It is customary for Trikru to burn their dead on funeral pyres. When they ready their dead for the fire, part of the ritual involves saying the phrase: "Kriken sonraun en branon. Kom graun, oso na graun op. Kom folau, oso na gyon op." (From the earth, we will grow. From the ashes, we will rise.)

Sky People, or Skaikru (Trigedasleng), is a term used by the Grounders to describe a person who came from the Ark. They are also commonly known as Arkers and on at least one occasion as Arkadians. The Sky People are descendants of humans who survived the Nuclear Apocalypse 97 years prior because they were already living in space or managed to escape in shuttles. With almost a century since the Apocalypse, the Ark merely needed to survive another two hundred years to ensure that the ground is viable for life. Little did most of the Ark population know that oxygen was running out, and soon enough, they would be forced to take their very homes through reentry, and begin life on the ground. Jaha mentioned that after the Culling there were 2,237 people on the Ark but they only have enough Exodus ships for 700 to get to Earth. In "Unity Day", Diana Sydney's dropship escape costs the lives of hundreds of Arkers as well as everyone on board her dropship. It is estimated in "The Calm" that there were no more than 1,000 survivors and at least 1,500 dead as a result. Project Exodus then took place and the Ark was brought to the ground. An estimate of how many survivors of the Ark made it to the ground in "We Are Grounders (Part 2)" is unknown since there are still several missing stations as of the Season Two finale. So far, Mecha Station, Alpha Station, Factory Station and Farm Station are the only four stations with known survivors with Factory Station having only one survivor, Mel.

Before the Nuclear Apocalypse, Tondc was Washington, D.C., the capital of the United States. During the Apocalypse, it was destroyed by a direct nuclear missile strike. Almost 100 years later, it is inhabited by Grounders. It appears to have maintained its political importance since it was the place where Lexa had brought all twelve Grounder Clans together to form an alliance with the Sky People in Rubicon. Mount Weather is a United States military underground bunker and missile silo launch facility located in the Blue Ridge Mountains in the eastern United States of America on Earth. It was constructed to house senior US officials in the event of a nuclear war. The Mountain Men are descendants of the original people who took shelter there during the Nuclear Apocalypse.

The Nuclear Apocalypse, also known as Praimfaya (Trigedasleng) or Apocalypse One, was a catastrophic event that took place in 2052, 97 years before the start of The 100 being sent down. It began when the Artificial Intelligence A.L.I.E. instigated a global nuclear exchange. Earth was left in ruins as a result, with the majority of inhabitants killed and the planet simmering in radiation. This apocalyptic event is also known as "the Bombs" or "the Fire". The Nuclear Apocalypse took place in 2052 after A.L.I.E. was accidentally released by Chris. A.L.I.E. quickly broke through the black ice encryption and the Faraday cage and began to hack launch codes from countries around the world. Chris attempted to stop her by releasing A.L.I.E.'s poison pill virus but that was unsuccessful. Soon after, A.L.I.E. successfully launched nuclear missiles from various countries around the world. This included 27 missiles launched from China toward the United States. A.L.I.E. planned to kill 6.5 billion people, in order to reduce the population. However, it killed almost 11 billion people.
