Earth (MS)

None (gone to Sanctum)

**Earth**, also referred to as "**the Ground**", was the original home of humanity. The series starts in September 2149, 97 years after a devastating nuclear apocalypse was caused by an A.I. called, "A.L.I.E.". While much of the ground recovered, with vibrant plant and animal life, atmospheric radiation levels remained at a significant level, only unaffecting those who have adapted to radiation.

Survivors in space believed Earth to be uninhabitable, but after a critical system failure in the Ark's life support systems, the 100 were sent to the surface in a last-ditch attempt to determine if Earth is habitable again. There they discovered that the Grounders have been living on the ground for generations. Throughout the first five seasons, various factions, including Grounders, Sky People, Mountain Men, A.L.I.E., and Eligius prisoners, fight for control of the ground.

Earth is destroyed by the death wave, with only one fertile valley remaining. However, on April 26, 2156, the valley is destroyed by the Damocles bomb, leaving the planet completely uninhabitable.

## History

File:Earth.jpg The Anomaly Stone was discovered in South America.
Long ago, at some point, an alien race from Bardo known as the Bardoans came to Earth and brought the Anomaly Stone there while they were traveling to different worlds looking for a new home. The Anomaly Stone was placed in Machu Picchu, which houses a secret observatory underneath the Temple of the Sun in the South American country of Peru.

In approximately 2040, Bill Cadogan traveled to Peru, where he found the Anomaly Stone in a hidden observatory under the Temple of the Sun. Cadogan decided to bring the Stone to the United States.

In this century, according to Monty Green, Earth has run out of oil, which led to the Eligius Corporation to send the motherships to space in order to find new resources. One ship, *Eligius III*, was also sent to colonize five potentially habitable worlds. Meanwhile, Earth has other problems, including the spread of the Russian Ankovirus, global warming, and humanity's overpopulation, which has reached to 11 billion people.

According to Bill Cadogan and Gabriel Santiago, Earth was terrible and it got worse after *Eligius III* left to other potential habitable worlds, referring the Earth's problem to the politics, the dying ecosystem and the memes.

During this time, a scientist named Becca Franko created an artificial intelligence named A.L.I.E., which became corrupted when it believed that human overpopulation will cause humanity to become extinct. On May 10, 2052, A.L.I.E. launched a Nuclear Apocalypse to kill 6.5 billion people, in order to reduce the population. However, it killed 11 billion people on Earth, causing the planet to be effected by radiation. The Mountain Men took shelter in Mount Weather to survive the Earth's destruction, while the Second Dawn members took shelter in the bunker. Other people all over the world were scrambling for bunkers to survive the apocalypse.

Two years later, when Becca fled the destruction of Polaris, she landed on the ruins of Earth, where she encountered several members of the Second Dawn on a scavenging mission. Drawn to the Anomaly Stone, Becca was able to use the Flame to open the Temporal Anomaly to Bardo, but advocated using Nightblood instead to rebuild the Earth and save what was left of humanity there. Bill Cadogan, the cult leader, refused, but his daughter Callie began recruiting people to become Nightbloods to return to the surface. Becca discovered "the final code" using the Flame which led to Judgment Day, the end of humanity which she refused to give to Cadogan. After learning of the Flame, Cadogan had Becca burned at the stake to get it, but Callie stole the AI and fled the bunker with her people, chased by her brother and Tristan who were also Nightbloods. Cadogan then led the remainder of the Second Dawn, now calling themselves the Disciples, to Bardo through the Anomaly.

To Callie's people, Becca became a martyr, known as the First Commander with each bearer of the Flame becoming the next Commander. Callie's group took with them 2,000 more doses of Nightblood to help save the other survivors they would encounter on their journey, eventually becoming the founders and ancestors of the Grounders. According to Titus, they were the first *Natblidas*. The Grounders adopted Trigedasleng, a language created by Callie as a child, as their primary language.

Many years later, the Grounders became tribal and primitive, and formed a dozen, different clans in what used to be North America. Other overseas Grounders were seen in Egypt.

For years, many Grounder factions fought in battles and conflicts, while they began surviving in a primitive world. The Mountain Men began surviving in Mount Weather, by staying inside, and using the Harvest Project, by capturing many Grounders, who are immune to radiation.

During the war with Mount Weather, Commander Lexa formed an alliance of twelve Grounder clans, known as the Coalition.

When the Sky People came to Earth from The Ark, they encounter many Grounders in the territory they land in. They began living on Earth, but after the Second Nuclear Apocalypse is caused by the failing nuclear power plants that survived the first nuclear apocalypse, the surviving Grounders and Sky People were forced to take shelter in the Second Dawn Bunker, where they formed *Wonkru*, a successor to the Coalition.

Six years later, after the Second Nuclear Apocalypse and the Damocles Event, Earth becomes uninhabitable forever, forcing the remainder of humanity to go into space where their new journey begins.

## Environment

On May 10, 2052, A.L.I.E. initiated the Nuclear Apocalypse that devastated the planet and drove humanity to near extinction. Over the following 97 years, much of the planet had recovered but became a very different place. Ecosystems changed, landscapes were reshaped, and life adapted. Much of the infrastructure had been destroyed or decayed. Lush forests grew throughout much of the Baltimore–Washington metropolitan area while further north became a wasteland.

The death wave destroyed approximately 96% of the Earth's surface leaving it as charred ruins. However, Shallow Valley was spared and continued to grow lush with plant life, as well as some animals and fish.

The valley was destroyed on April 26, 2156 by the Damocles bomb launched by Paxton McCreary. That left the entire planet a wasteland and uninhabitable. Thirty years later, Earth was still uninhabitable and showing no signs of recovery, causing Monty Green to declare that the Earth would never recover and would be uninhabitable forever.

## Minor Locations

### Art Supply Store

Also known as **Finn's Bunker**, it is the name given to a bomb shelter discovered by Finn Collins. The bunker's original purpose was to serve as a shelter from nuclear bombs in the case of an apocalypse, but the owners possibly never made it. Among the items in the bunker is a picture of a family, presumably the people it originally belonged to. Clarke speculated that even if the family had been able to make it, they would've run out of food within a few years or gone stir crazy, opened the bunker and died of the radiation. The Delinquents used it for supplies as well as a place to take shelter. While it still has food, the food is long out of date and is of no use.

Because of the instability of the Delinquents' society, Finn convinced Clarke Griffin to keep the bunker a secret in order to have a place to hide if the needs arose. When John Murphy was out to get Charlotte, Finn and Clarke hide Charlotte down in the bunker. After Clarke and Finn Collins fall asleep, they wake up to find that Charlotte ran away. Later, Clarke and Finn sleep together in the bunker. After Raven Reyes arrives on Earth, Clarke takes Raven to the bunker to look for a transmitter to fix the radio. Raven found a remote-controlled car and used it for parts to successfully fix her damaged radio.

After capturing Delano, Finn takes Bellamy Blake, Murphy, Zoe Monroe, and Sterling to the bunker to question Delano, ending in Finn executing him. Finn returns with Clarke to the bunker one last time when they flee from Acid Fog, coming face-to-face with Delano's corpse.

### **Lincoln's Cave**

Lincoln kom Trikru brings Octavia Blake back to his cave to treat her injuries. After Lincoln is captured and tortured by the Delinquents, Octavia helps him escape and he returns to his cave. Octavia meets up with Lincoln again in his cave in "Unity Day" and together with Finn Collins, they arrange the bridge meeting between Clarke and Anya. Octavia finds Lincoln in his cave, packing up his belongings. He asks her to leave with him but she ultimately refuses and decides to stay behind with the Delinquents. Lincoln returns to the cave after outrunning Reapers and runs into Finn who came in search of coagulant to save Raven Reyes' life. Finn convinces Lincoln to use the Reapers as a distraction to help the Delinquents during the final battle. The cave is subsequently abandoned after this.

### Oil Rig

Located away from the mainland, the *Floukru‎‎* live on an **oil rig**.
They use boats and oil tankers for transportation.
It is unclear how Luna found the **Oil Rig** after she abandoned her conclave.

It was abandoned in Season Four after all of *Floukru* died of radiation poisoning.

### Abandoned Bridge

It is a minor location in Season 1.

It is the place where Anya kom Trikru and Clarke meet. During the meeting, Jasper Jordon sees Grounders in the trees. After Jasper realizes that they are aiming at Clarke, he tells her to run and fires at the woods. He manages to take down 2 of the attackers. Anya gets shot, but she gets away.

Raven makes and plants a bomb on the bridge. Finn Collins, carries her away before she gets blown up. The bomb is hit and it destroys the bridge, harming and killing some Grounders including Tris.

### Old Army Bunker

The old army bunker was located nearby a body of water and ruined buildings. The depot was designed to hold supplies for a long time, such as guns and blankets. The bunker is full of cobwebs and thus uninhabitable. Most of the supplies are bad, ruined or stolen.

### Depot Ruins

Clarke and Bellamy come across ruins. They search and find a door to the depot. Inside, they find barrels full of grease and guns. Most of the bullets are stubs unfortunately. Clarke finds blankets but Bellamy isn't impressed. Dax stalks them as Clarke and Bellamy are in the depot. The two later bring the guns back to camp to provide protection from the Grounders.

Marcus Kane tells Bellamy that a search team from Camp Jaha returned to the bunker and found two barrels of guns and a barrel full of ammo. Bellamy admits that they should've searched it harder.

### Parking Garage

It was found by Octavia. The garage was abandoned, during the nuclear apocalypse, leaving behind many cars. Reapers have access to the garage, as seen when they attack and kill Sgt. Scott and another guard when turning on an old Christmas mp3 player. It is then once again abandoned when Octavia and Bellamy manage to knock out Lincoln.

### National Zoo

Lexa, Lexa's bodyguard and Clarke stumble across the ruins of the **National Zoo**when crawling through an old sewer grate, while running from Puana. The zoo is Puana's (Gorilla's) "Feeding grounds." Puana kills Lexa's Bodyguard and the Clarke shoots it multiple times. Then Puana awakes from her wounds, Clarke and Lexa jump over a railing and lock themselves into a holding cage. They manage to escape, locking Puana for a while.

### Ilian's Farm

Ilian and his family lived on an old farm. They found the farm after the first nuclear apocalypse. There, they took care of animals and grew crops.

### Other Minor Locations

* Eden's Pass
* Rendon
* Farm Station
* Temple of the Sun `in South America`

## Trivia

* At the start of the series, 97 years after the Nuclear Apocalypse, Earth was still irradiated. However, Grounders and Sky People can survive on the ground due to having greater immunity to radiation than pre-apocalypse people.
	+ Sky People gained immunity due to genetic engineering and growing up in space exposed to solar radiation.
	+ Grounders gained immunity due to natural selection and Nightblood serum.
	+ Mountain Men did not go through this process and are extremely vulnerable to the atmospheric radiation on the ground.
* Earth was ravaged again by the death wave (also called *Praimfaya*). After five years, in 2155, the atmospheric radiation reduced to habitable level for Grounders and Sky People.
	+ During the five years, Nightbloods were the only ones who could live on the ground. Clarke and Madi spent those years living in Shallow Valley while all other survivors either hid in the Second Dawn Bunker or escaped to space.
	+ It is unclear how the people from *Eligius IV* gained increased radiation immunity. While six years after the second nuclear apocalypse radiation is habitable for Grounders and Sky People, it is still significantly higher than it was before the first nuclear apocalypse. Unlike those from *Eligius III*, they were not given the Nightblood serum. However, they were exposed to solar radiation during their hundred-year space journey.
* In the Season Five finale, the Damocles Event destroyed Shallow Valley and caused Earth to become fully uninhabitable.
* Earth has/had an Anomaly Stone. It was originally located in a hidden observatory beneath the Temple of the Sun in South America's Machu Picchu before being moved to the Second Dawn Bunker. It is unknown what became of it following the Disciples' relocation to Bardo as it didn't appear to be in the bunker when *Wonkru* occupied it.
