The Second Dawn Bunker, also known as "Becca's Crypt" or the "Level 12 Bunker" was built and used by the Second Dawn cult before and during the first nuclear apocalypse. It was later used by Wonkru to survive the Second Nuclear Apocalypse.
The bunker has six levels, labeled A through F. Level C contains the hydrofarm and the water recycler, which are completely self sustainable should the rest of the bunker fail. The cafeteria is also located on that level. Level D contains the generator. The bunker also includes underground aquifer with a filtration system, oxygen and air scrubbers, medical area, and airlocks. Supplies left behind include hazmat suits.
The Second Dawn cult decorated the bunker with signs, flags, and posters with their logo and adages. Near the entrance, there is a flag that reads "From the ashes, we will rise." The cafeteria includes posters with quotes "blood must have blood" and "your fight is over". All three Second Dawn adages became important Grounder sayings.
When the bunker was controlled by the Second Dawn, it had a room that was used by Bill Cadogan as his lab. When Wonkru took control of the bunker, this room was changed into a rec room. In both instances, the room contained a piano and the Anomaly Stone, though the Stone was buried in the floor during Wonkru's reign.
The bunker was built sometime before the Nuclear Apocalypse by the doomsday cult Second Dawn which was led by Bill Cadogan. When the Nuclear Apocalypse occurred, 1,104 people made it into the bunker, 92% of the Level 12's slated to live there. It held the Second Dawn for two years before the cult split, one faction led by Callie Cadogan leaving to return to the surface using Becca Franko's Nightblood while the rest became the Disciples and left Earth for Bardo through the Temporal Anomaly. At some point later, the Anomaly Stone was buried in the bunker's floor, presumably by Azgeda as an Azgeda symbol was burned into the floor over the Stone's burial site.
According to Gaia, Becca is buried in the bunker, implying that her ashes are kept in there after she was burned alive at the stake, but A.L.I.E. 2.0 managed to "crawl out of the flames", like it said in the notebook. The Flamekeepers came to believe that the phrase "salvation lies within" referred to the Polaris escape pod that Becca had come to Earth in which was positioned over the bunker entrance.
According to Thelonious Jaha, while he knew of the possibility of the bunker's existence, he didn't consider it for the Delinquents to use when they arrived on Earth as its existence couldn't be proven.
With the approach of the Second Nuclear Apocalypse, Jaha sought out the bunker as a possible means of survival, eventually locating it long-since abandoned beneath Polis. The bunker became the home of Wonkru for six years during which time they were trapped underground by the collapsed Polis tower. The bunker was eventually freed by the Eligius prisoners and remained the home of Wonkru until the clan marched on Shallow Valley following the destruction of the bunker's hydrofarm by Octavia Blake in order to force Wonkru to follow her to the valley.
125 years later, Clarke and her friends return to the bunker and the regenerated Earth during their conflict with the Disciples, the descendants of the cult that had originally built the bunker. The group decides to live in the bunker again until they can build their own shelter on the planet's surface. The bunker is severely damaged when the Disciples send a bomb through the Anomaly. Though the airlock contains the blast, the corridor between the pit and the rest of the bunker collapses as a result. However, the Anomaly Stone is rediscovered by Raven Reyes, Eric Jackson and John Murphy, providing them with a way out while most of the rest of the group remain trapped elsewhere in the bunker. Raven later returns with the remaining Eligius Prisoners who open the corridor again, allowing everyone to reach the Stone and leave.
Throughout the Series
In The Four Horsemen, Thelonious Jaha told Clarke Griffin and Bellamy Blake that there might be a bunker that could save more people. They discover a bunker but realize it is not radiation-proof. In God Complex, Jaha, Marcus Kane, Monty Green, Indra and Gaia discover another bunker in Polis. They realize the first bunker was a decoy and that people can survive in the Polis bunker. In Die All, Die Merrily, Clarke and Jaha go against the rules of the conclave, and move most of Skaikru and Niylah into the bunker. The only Skaikru left outside the bunker are Kane and Octavia in Polis; Raven at Becca's Lab; and Monty, Harper, Jasper, and several others at Arkadia. In The Other Side, the bunker becomes over populated with approximately 1,564 people. In The Chosen, Kane and Jaha gas their area of the bunker and sacrifice 364 Sky People in order for there to be enough oxygen and food for everyone else in the bunker as to make room for everyone. In Praimfaya, Octavia, with Bellamy's and Indra's encouragement, takes the lead of the people within the bunker.
In Nevermind, Clarke Griffin appears in the bunker in her Mindspace, confronting Blodreina. In What You Take With You, while under the influence of red sun toxin, Octavia hallucinates herself in the bunker's fighting pit, chained down in the middle of the floor. Octavia is confronted by a hallucination of Charles Pike for her actions, both in the bunker and outside of it. Octavia admits that she wants redemption for her actions, but is interrupted by a manifestation of her dark side as Blodreina who demands that Octavia kill Pike again. When Octavia refuses, Blodreina prepares to execute Pike herself, but Octavia recognizes the speech Blodreina gives as the same Pike gave when he executed Lincoln. Octavia saves Pike who disappears and Octavia and Blodreina battle in the middle of the arena. Octavia manages to kill the manifestation of her dark side, declaring herself to be "Blodreina no more." She then wakes up in the Verge on Sanctum.
Second Dawn cult
In "Praimfaya", Indra says there are 1,200 inhabitants within the bunker. By "Pandora's Box", there is only 814. After the bunker is opened, they start using the space above ground as well as the bunker. Some the inhabitants also defect to Shallow Valley or are killed. After The Warriors Will, Wonkru left the bunker to march onto Shallow Valley, leaving the bunker uninhabited.
Many members of Wonkru, who survived in the bunker for six years, are still alive but no longer living in the bunker. Some defected from Wonkru after the bunker was opened while others remained.
Several people were on Clarke's list or were seen in the bunker at the end of season 4 but have not been seen in season 5. They may have died at some point though their deaths are currently unconfirmed.
During the six years the bunker was sealed, 386 people died including:
Other former residents died after the bunker was re-opened in "Pandora's Box", including:
Clarke and Murphy briefly lived within the bunker but left before the culling. Clarke, Madi, and Echo briefly lived within the bunker after it reopened. Echo left to spy on the prisoners, while Clarke and Madi drove away after Gaia inserted the Flame into Madi.
Bellamy Blake briefly lived within the bunker but left before the culling. Bellamy, Monty Green and Harper McIntyre lived in the bunker briefly after it was re-opened in "Pandora's Box". They left the bunker with Wonkru when it marched on Shallow Valley.

Notes and Trivia
- Out of characters introduced in seasons 1-4, Raven Reyes is the only character to survive season 5 who hasn't been in the bunker. Many characters introduced in season 5, including Miles Shaw, most Eligius prisoners, and Jordan Green, have also not been in the bunker. Raven and Jordan would later visit in Season Seven.
- In "The Dying of the Light," its revealed that the Anomaly Stone was buried in the floor of Cadogan's lab which later became the rec room during Wonkru's time in the bunker. An Azgeda symbol burned into the floor over the spot suggests that they were responsible, though when, how or why they did it is unknown.
