DiMA

DiMA is an escaped prototype synth developed by the Institute who now leads the Acadia synth refuge on Mount Desert Island in 2287.

Background
DiMA is an experimental second generation synth prototype, a "brother" to Nick Valentine. The two were the first synths capable of independent thinking and judgment. One of the Institute's experiments had to do with how synthetic brains could process personality, and so they adapted two synths for their experimentation. DiMA was allowed to develop his based on experience, while Nick was an attempt to copy a personality matrix into a synth brain - the original Nick Valentine's. The two underwent the same kind of lengthy experimentation, every day for months, strapped down to a workshop table. Immobile and operated on as the Institute rooted around in his artificial brain. Eventually, though, he managed to orchestrate an escape, taking Nick with him. The failsafes stripped their memories of the Institute, but the two were finally free. Unfortunately, Nick did not recognize his brother and attacked him on the spot, still thinking he was the pre-War Nick Valentine. Beaten and damaged, DiMA was abandoned... But survived.

It was around 2178 that DiMA landed at Far Harbor, trying to find a safe haven for synths. His first choice of location was a pre-War submarine pen, still housing the derelict USS Democracy. DiMA used the base's computers to expand his limited storage capacity, offloading the oldest memories into the pen's data banks as he labored to make a better place. In mid-23rd century he was found by Faraday, an escaped third generation synth. The two became inseparable, despite DiMA's stubborness, as Faraday's technical acumen was essential to keeping the prototype synth online.

Eventually, he handed the base off to the Children of Atom, cast out of Far Harbor for their belief, and moved to found a safe haven at Acadia. As the synth refuge grew, he realized he needed a lifeline to the outside world. The candidate? Far Harbor. In return for their cooperation, Acadia would supply the town with fog condensers to keep the radioactive fog at bay. Unfortunately, following initial forays, it turned out that Far Harbor was hostile to synths. In response to attacks and harrassment, DiMA formulated a plan to pacify the town's residents. Captain Avery was kidnapped, murdered, and replaced with a synth agent, unaware of her identity, who slowly but surely nudged the town towards tolerance. In the event the town discovered the truth, he also prepared a killswitch that would shut down the wind turbine and cut power to the fog condensers, allowing the Island to consume Far Harbor. As with other unpleasant memories, he forced himself to forget about it.

DiMA continued to be friends with Confessor Martin of the Children, headquartered at the old submarine pen, now named the Nucleus. One of his most notable actions, to ensure the survival of the Children, was to seal away the nuclear missile launch keys. Primarily out of sentiment: The Children were the first to accept him for who he was with no reservations. Unfortunately, when Martin passed, the friendly relations between the synths and the zealots deteriorated due to the election of the new High Confessor: Tektus, who was a megalomaniac fanatic bound on implementing a final solution for Far Harbor.

DiMA has been working on a solution ever since, together with his synth followers: Faraday and Chase. Faraday's upgrades helped him rectify the problems with memory and overcome the limitations of his original design. The selfless synth has no recollection of his sins, as they are all under lock and key inside the Nucleus... <!-- An execution Cog's journal What's done is done What Atom requires

DiMA: ''"You know, when I first climbed this mountain, above the fog, I thought to myself: now here is a metaphor worth taking in. You've entered a place of clarity. Understanding. Peace. While you're here in Acadia, synth-kind welcomes you, as long as you welcome us.

The Sole Survivor: "I came here looking for Kasumi Nakano." DiMA: "Really? I'm impressed. Few would brave the kind of journey you've had for the sake of someone else. Kasumi is here. She's safe and unharmed, and you're free to see her, if you'd like. Before you do, though, tell me: Do you think Kasumi is a synth?" Nick Valentine: "We're not answering any more questions until you play straight with us. Just who the hell are you, really? There's only one synth with that kind of face and a mind of his own, and I only see him when I look in a mirror." DiMA: "Nick!? It... it can't be you..." Nick Valentine: "Don't give me that. What are you trying to pull? I've never seen you before in my life. DiMA: "Please. If you're willing to give me a chance, I can explain." The Sole Survivor: "Is this a joke? Do you really know Nick?" DiMA: "Let me tell you what I know, and you can judge for yourself. We were prototypes, Nick. The first synths capable of independent thinking and judgment." Nick Valentine: "{{Tooltip|Keep talking...|horrified at the realization that this synth does know who you are / Suspicious" DiMA: "{{Tooltip|One of the Institute's experiments had to do with how our brains could process personality. If we could handle individualized feelings and behaviors. I was allowed to develop mine based on experience. But with you, they wanted to try transferring an entire personality into you. It took several attempts before the personality imprint worked. I saw you wake up not knowing who or what you were so many times... I couldn't let them do it to you anymore. We were the only two prototypes they made. I literally saw myself in you...|Sad}} {{Tooltip|You were my brother, Nick. I helped you escape the Institute. We left together.|emphasize brother / Sad}}" Nick Valentine: "{{Tooltip|If I were your brother, I'd remember!|Suspicious}}" DiMA: "{{Tooltip|That's where you'd be wrong. This happened over a century ago. There's... there's only so much memory that can fit into the prototype brains we have...|Sad}}" Nick Valentine: "{{Tooltip|I've heard enough...|Stern}} {{Tooltip|I think you and I need to talk about this. Maybe not now, though...|talking to the player / Concerned}}" The Sole Survivor: "Nick. Is he really your brother?" Nick Valentine: "{{Tooltip|If he is, it's news to me. Can synths even be related? Just because we're from the same assembly line, does that make us family?|Concerned}} {{Tooltip|I gotta think about this...|Depressed}}" The Sole Survivor: "Is it really possible that you wouldn't remember any of this?" Nick Valentine: "{{Tooltip|You mean between the Institute failsafes, the beatings I've taken over the years, and plain old age? Or are you buying his whole "there's only so much room up there" argument? I don't know... Not like we've got the instruction manual...|Puzzled}}"''

DiMA: "{{Tooltip|Nick, I don't need you to believe me, I'm just glad to see you again. Whenever you're ready, I'll be here.|sincere / Sad}} {{Tooltip|Now, about young Kasumi... It's important that you understand exactly why she's here. I asked you before if you think she's really a synth. If you could indulge me with an answer...|Thinking}}"
