Atlantis Beckett

Atlantis Beckett (Atlantis Riverly Beckett) is a major character introduced in Season 2 of The Boy from the Bunker series and is portrayed by Vanessa Morgan in the books. She is a member of the Second Bunker located east of the dams beside Blood Riders territory and was evacuated from her shelter and taken into Basilisk by Sol Riverly and Eryx Riverly.

Atlantis was originally a member of the clan Basilisk when she was an infant, but her mother, Zara Beckett, decided to take shelter in one of the nearby bunkers when the war was impending close to their home, and so she grew up in The Bunker Coalition (referred to as the Second Bunker) alongside 9 other residents for 13 years. After arriving at Basilisk with her mother, she learns that the former Nobel Sovereign Eryx Riverly is her father and Sol Riverly - the current Nobel Sovereign - is her paternal half-sister. Chessca Jones also shares a sisterly-role alongside Sol as it is stated that the three of them are sisters in 'The Invaders' (S8x01x04). Despite not having a great relationship with Sol when (Sol) first discovers they are sisters, their bond strengthens after Atlantis suffers an injury and develops monoplegia (paralysis in her left arm) as this causes Sol to grow protective of her. Their bond is once again strengthened when Atlantis' mother is killed and Sol realises that she is the only family Atlantis has left, and subsequently steps up her role as big sister. In the epilogue of Season 10, Atlantis is revealed to be in a relationship with Bas Blackwood (which Sol and Chessca teased in Season 9) and has four children with him: twins Henry and Haven Blackwood, a son - Brody Blackwood, and a daughter - Zara Blackwood, named after Atlantis' late mother. Wynn Bell and Harlow Blackwood are her brothers-in-law, although, she has been considered a guardian of Harlow for a long time prior as he was a young child when her relationship with Bas began (and Bas is also Harlow's guardian), and she was often the caregiver for Harlow whenever Bas went out on missions.

 Season 2 

Atlantis' bunker is evacuated by an outside clan known as Basilisk and she is promptly taken to their camp where she learns that her father, Eryx Riverly, had given her sister Sol Riverly the instruction to open the nearby bunkers for what she (Sol) didn't know was an attempt for Eryx to reunite with Atlantis and her mother, Zara. Relieved to have found them, Eryx forces Atlantis into training for his plan for Atlantis to overthrow Sol as Nobel Sovereign. At the same time, he denounces Sol's title and sends two of his loyal followers - Ellery and Adair - to abduct and kill Sol. When Atlantis realises that the sister she so badly wants to know is missing, and presumed dead, it isn't long before her suspicions begin to fall on her father and she conducts a plan alongside Wynn, Dreea and Kodiak to help bring Sol home which includes Atlantis temporarily taking up the position as Nobel Sovereign.

 Season 3 

After having worked closely with Dreea to help bring Sol home safely, Atlantis is hopeful that Sol will open up to their relationship as sisters - after they both agreed to the decision to execute their father, Eryx Riverly, after the crimes he unleashed on their family. However, despite Sol's gratitude at returning home - and her knowledge at how Atlantis played a vital role in everything, Sol still shows little-to-no interest at having a relationship with Atlantis. Yet, when a deadly virus is sent into Basilisk's camp from Noah Rule - King of Blood Riders, and their new ally - The City of Targo, Sol is forced into making a sacrifice to save Atlantis' life and once again, the two sisters are brought closer together. After Atlantis has recovered from the virus, Sol asks for her to accompany her when visiting her bunker, but they soon run into trouble. When they are both under attack by stray fighters from Blood Riders, Atlantis makes a sudden decision to push Sol to the ground to protect her from a shot she can see firing (that Sol is unaware of) and returns the favour by subsequently saving her life. However, after Sol has finished taking down the last of their attackers, she begins to wonder why Atlantis hasn't pulled herself up from the ground yet, only to discover that Atlantis had been severely wounded when trying to save her life. There is a giant open-wound from Atlantis' inner elbow down to her thumb and despite Sol doing all she can to treat her in the forest, they arrive back at Basilisk and Atlantis is treated by Aeryn only to learn how serious her injury is. Later on, when Basilisk are announced war on by Blood Riders, Sol makes a decision to keep Atlantis in a secret shelter inside Basilisk to protect her from the war which leads Atlantis into believing that a relationship between the two of them isn't entirely out of the picture.

 Season 4 

After having a bad experience the last time she left camp, Atlantis tries to sneak her way onto a mission and leave Basilisk, but is promptly noticed by Sol. She begins to persuade her way into leaving with the group and impressed with her determination, Sol allows her to come. When the group arrive at Blood Riders' lab to raid them for medical supplies an answers to the serum - which is haunting Elara with violent hallucinations and visions - they are discovered by Rogue Rule and a group of his fighters. When all of the people from Basilisk are captured and interrogated, Sol and Dreea managed to discreetly communicate and initiate a fight back. As everyone else helps to take down the people from Blood Riders, Atlantis finds herself in the most danger of all as realisation sets in that she is unable to fight back. After arriving back at camp, Atlantis reveals to Sol that she lied about the damage done to her hand as she didn't want to upset her or increase her undeserved-guilt over how serious her injury is. Atlantis confesses that she has developed monoplegia and her left arm is completely paralyzed. Despite it being under unfortunate terms, it ends up making their connection even deeper.

 Season 5 

When Sol approaches Atlantis and asks to use her bunker to hide Elara inside, Atlantis agrees and travels there with Sol, Wynn, Aeryn, and her mother - Zara to make sure supplies are dropped off and the bunker is ready for Elara's stay. As Sol is looking around the bunker, she notices a framed photograph on one of the tables in the hall. Immediately, she recognises her father in the photo and realises that the two, young girls on either side of him are herself and Atlantis. Atlantis makes her way over and informs Sol of what she knows about the photo - telling her how old they are when it was taken, and what was happening. She reveals that Sol was five in the photo and Atlantis was two and it was taken just before Atlantis and her mother went into hiding. It is then that Sol learns that Atlantis has always known she has had a sister and was fortunate enough to have a photo of Sol all those years when she was in the bunker, but Sol had no knowledge of Atlantis' existence until her arrival at Basilisk in Season 2. When Atlantis notices Sol's conflicted feelings over the photo - mainly due to their father being centre-frame - Atlantis takes the photo out and rips Eryx out of the photo so that only Sol and Atlantis are there. This small gesture from Atlantis is what later on brings Sol to accept her as family and is a pivotal movement in their relationship. When they later leave the bunker after dropping Elara off and plan to meet up with Kodiak, Dreea, Quill who they have purposefully led into The City of Targo's capture, the group are under attack by Blood Riders and despite Sol and Wynn's best efforts to protect everyone, Zara ends up being captured by a Rider and is killed in front of them all. As Atlantis tries to run after her mother and subsequently put her own line on the line, Sol stops her by restraining her and informing Atlantis that she can't lose her because "(you're) my sister". Atlantis is still desperate to reach her mother, but finds just enough strength in Sol's words to hold herself back and allows her sister to take her home to safety. Later on, Sol visits Atlantis in her tent where Zara's bed is untouched with a pile of her clothes resting neatly on the edge, and she notices that Atlantis seems to be struggling with how to deal with her grief on her own. As the two sisters sit beside each other on the bed, Atlantis feels a part of her heart begin to heal when Sol informs her that she "didn't grow up with a sister, but (she) has one now and (she) gets to spend the rest of (her) life getting to know (her)." Atlantis is hopeful at moving forward and recovering from the death of her mother now that she knows she has the support of her big sister around, however, things take a devastating turn for the worse when Sol has to sacrifice herself over to The City of Targo to save Wynn, Elara, Atlantis, and the entirety of Basilisk. After recently having lost her father, and her mother dying only days before, Atlantis must now face the loss of her big sister and the last member of her family she has left, Sol.

 Season 6 

8 months after her sister Sol was taken by The City of Targo, Atlantis learns about Wynn's plans to travel through the DeadLands and bring Sol home after an announcement was made to the people of Basilisk that the remaining people of Blood Riders would temporarily be staying within Basilisk as part of an alliance. Atlantis figures out the Sovereigns' true motive and approaches them in the Quarters, insisting that she join them on their rescue mission. Whilst Dreea and Kodiak are hesitant to let her join - as it is an incredibly dangerous mission and they know Sol wouldn't want her put at risk - Wynn argues for Atlantis and emphasises that he understands how it feels to lose a sibling, agreeing that Atlantis should be allowed to go with them to The City. Dreea and Kodiak cave with the condition that Wynn trains Atlantis so she is able to defend herself if it comes down to it and when the time finally comes for the small group of people at Basilisk to travel to The City, Atlantis is with them. Once through the DeadLands, she spends majority of her time the refuge with Bas, Quill, Elara, and the rest of her people. When stakes rise and the risk of losing Sol for good becomes more prominent than ever, Atlantis follows the Sovereigns into The City to try and help spark a memory within Sol, but there is no avail. As Atlantis tries to explain to Sol that they are sisters, Sol quickly shuts her down and informs Atlantis that she doesn't have a sister. Whilst Atlantis knows that the only reason Sol is saying that is because she has had all memories of Atlantis (and everything else) erased, it still doesn't hurt any less to hear it, especially after how long it took Sol to accept her in the first place. It is only after Sol is induced into a vision with Elara that her memories are restored Sol learns how many people are waiting for her to come home, and she uses all of the strength she has left to pull through the horrible effects of The Alteration and memory erasure and return to her family - Atlantis being one of the first people at her side. After escaping The City and loading up on the half-bus for their venture through the DeadLands, Atlantis sits beside Chessca and keeps her sister company for the entire journey home.

Fun Trivia: 

Atlantis was born at Basilisk in moved into her bunker shortly before she turned 3. Even though they were both too young to remember, Atlantis and Sol often interacted with each other at camp after Moira's death after Eryx's suggestion to warm Sol up to Atlantis before he broke the news to her that they were sisters.

When her father (Eryx Riverly) began his relationship with her mother (Zara Beckett), Eryx arranged for his current (pregnant) wife - Moira Riverly - to be killed which would allow him to start a new family with Zara. Had Moira not had been killed, she would have given birth to a son named Rain Riverly. He would have been Atlantis' half-brother.

Atlantis kept her mother's maiden name instead of taking up her father's surname (making her Atlantis Riverly) as Eryx didn't want people to discover that he'd had an affair on Moira and had a second child outside of his marriage as he worried it would reflect badly on his position as Sovereign. Atlantis also spent majority of her childhood growing up without the presence of her father (as she was living in a bunker with her mother), and it therefore seemed fitting that she kept the same surname as her mother.
