Mount Weather War

The Mount Weather War is an important armed conflict between the Grounder/Sky People Alliance and the Mountain Men of Mount Weather. The war unofficially began at least fifty-six years before the start of series when the Mountain Men began to abduct Grounders to use their bodies to filter radiation.

The war ended at the battle of Mount Weather on the 2nd of November 2149 with a Sky People victory and the almost total annihilation of the Mountain Men with Carl Emerson being the sole survivor.

Background
Fifty-six years ago, when the Mountain Men first discovered the Outsiders were able to walk above ground, they began conducting experiments on them. Through the use of the Cerberus Project, the Mountain Men would collect Grounders using the vicious Reapers they created. Then through the Harvest Project, the Mountain Men would use the Grounders to help filter the radiation out from the Mountain Men's blood.

They eventually progressed onto using the Sky People's bone marrow, leading to all-out war and later the irradiation of Mount Weather by the Sky People.

Events
In The Calm, Monty is kidnapped by Mountain Men, unbeknownst to the rest of the Delinquents.

In We Are Grounders (Part 2), the Mountain Men storm the camp of the Delinquents, taking in the remaining amount from the battle with the Woods Clan. Clarke wakes up in quarantine, only to find herself locked in a room across from Monty. She sees a sign that says Mount Weather on it and looks on in fear.

In The 48, Clarke is still trapped in the white room. She looks across the hall and finds the room where Monty was before is empty and sees a person in a hazmat suit. Clarke breaks out of the room and takes the girl in the hazmat suit hostage demanding to see her friends. Clarke reaches level 5 and the mess hall and before a Mount Weather citizen alerts the others of a containment breach and Clarke is knocked out by guards. Clarke later awakes in medical and introduced to Dr. Tsing and Dante Wallace, Clarke again demands that she see her people and Dante Wallace allows her to, bringing her to the mess hall. There, Clarke is reunited with Jasper and Monty. Later, during a meal Monty and Jasper are trying to convince Clarke to try the various food but Clarke refuses to eat Mount Weather's food and claims everything is too good to be true. Jasper leaves her and goes to find more chocolate cake and is offered some by a girl named Maya, the same girl Clarke took as a hostage at the beginning of the episode. Clarke approaches them and apologizes to Maya, however, she takes her keycard. Clarke searches for an exit and finally finds one but is pursued by Jasper and Maya. Clarke prepares to pull the lever but Jasper tells her that if she does, everyone in the Mountain will die so Clarke doesn't pull the lever and is taken by guards. At the end of the episode, Clarke enters the dorm and finds a box of oil pastels on her bunk from Dante Wallace in order to foster trust. At dinner that night, Clarke finally eats their food and is filled with temporary contentment.

Aftermath
After the irradiation of Mount Weather, only two Mountain Men who had received the marrow treatment survived: Cage Wallace and Carl Emerson. As Cage tried to escape through the woods, he encountered Lincoln, whom he had turned into a Reaper once before. Lincoln kills Cage, leaving Carl Emerson as the sole survivor.

Three months after the war, several dozen Sky People moved into Mount Weather. However, Emerson had told the Ice Nation how to activate the self-destruct mechanism for Mount Weather. The Ice Nation sent an assassin who successfully blew up Mount Weather, killing 49 Sky People inside, 35 of whom were from Farm Station. This led to the Ice Nation Queen, Nia, being brought in for treason and eventually killed by Lexa. Roan, the new king of the Ice Nation, captured Emerson and sent him to Clarke and Lexa. Instead of killing him, Clarke chose for him to be banished.

Later when Clarke and a group of others returned to and abandoned Arkadia, Emerson appears disguised as a grounder systematically capturing each member roaming around Arkadia. During this process, Emerson ended up killing Sinclair by mistake. Clarke and Bellamy being the only ones not captured, go after Emerson and find him holding everyone captive. Emerson had Bellamy turn himself in, then Emerson grabs Clarke. Emerson sealed the door with everyone inside of the room, cutting off the oxygen, to make Clarke feel what he felt. Clarke fought to free her friends, but Emerson managed to take her down to make her watch everyone die. Clarke, however, surprised Emerson with A.L.I.E. 2.0, and the AI entered Emerson neck, causing him to bleed out of his eyes, nose and neck, killing him. Clarke freed her friends from captivity, and the last Mountain Men was finally dead.
