Yeah, so because Wikipedia and DC Comics Wiki suck at keeping up with Legion, I'm going to put Nura's entire history here, and update it as the comics continue. I'm doin this because I love ya all and some of you are interested in Nura's background.
Ya ready?
LET'S RUMBLE!
Nura Nal's life begins with her birth unto her parents, two Naltorians of very strict and focused commands. Nura was raised with the notion that she should be an obedient and honorable daughter and obey her parents every wish and command. She was given the best education and trained in combat since she could first pick up a staff to spar. Her parents wished for her to follow a path in law enforcement, which would bring much notice to the Nal family. Nura complied for quite some time, withdrawing into herself, and building up quite the tension and unbridled rebellion that would later pop at the tender age of fifteen, and enable her to go against her parents' wishes and values in spite.
Eventually, at sixteen, she defected from Naltor just as she was finishing Precommando training, when she heard of an elite group of young rebels that were against the current
adult regime. They were called the Legion of Super-Heroes...and she joined them happily.

On Naltor, natives are gifted with the ability to see the future. But where others see 20 seconds ahead, Nura Nal saw 30 seconds. This led her into law enforcement, but she left her training as a Precommando to join the Legion. On Earth, her fellow Legionnaires regarded her as somewhat of an airhead because her visions often left her oblivious to her present surroundings.
Dream Girl returned to Naltor with a group of Legionnaires when thousands were driven mad by "dream deprivation." The Legion noticed that only "underagers" were affected and soon uncovered the truth. The Public Service technology used to monitor underagers was itself negatively affecting Naltor's youth. While on Naltor, Nura received a particularly disturbing vision of great catastrophe. Naltor's High Seer had seen it as well, and sought to spare his people from experiencing the vision.
Dream Girl's began to encounter blackness in her visions. Part of her knew what this meant. When the Legion's battle with Lemnos came to a head, the villain sent suicide bombers into the Legion plaza and headquarters. As the building collapsed, Dream Girl guided others to safety, but perished herself when the plaza fell.
Brainiac 5 had always acted as though Dream Girl were an anomaly or an annoyance. In truth, he was in love with her. Upon her death, he acted immediately to preserve her body-and, he hoped, her soul. He deduced that a person's soul was merely energy and he housed Nura inside one of his force fields to keep hers from escaping. Her body remained in suspended animation until he could finalize his plans to resurrect her. Her fellow Legionnaires held a special memorial where one Legionnaire at-large, Reflecto, was delusional that she'd been his girlfriend.
Brainiac 5's plan involved using the powerful mental powers of their former foe, Lemnos, to restore Dream Girl's psyche and soul to her body. Brainy told few of his plans and soon absconded with Dream Girl's and Lemnos' bodies. He piloted an ancient L.E.G.I.O.N. craft into space along with Light Lass and Element Lad and Atom Girl, all of whom were drafted to help him reanimate his love. Using the power of a pulsar star plus Lemnos and the Legionnaires ... something happened. Dream Girl's body disappeared. Brainy was furious. But later, while sleeping, Dream Girl visited him. She was fully cognizant but now existed only on this metal/astral plane. Truly, a "dream" girl.
Meanwhile, Naltor's High Seer was demanding the return of Nura's body and Dream Boy (Rol Purtha) arrived to replace Nura in the Legion. Dream Boy was the first to learn Dream Girl's new state of existence when he receivede a visit from Dream Girl in his sleep. He soon revealed this to others, including Brainy. Brainiac 5 kept this a secret, but Dream Girl was not limited to visiting him. Saturn Girl also discover her presence when she was forced to enter Brainy's mind in his sleep. Phantom Girl also received a vision from her.
In this spectral form, Nura could easily have chosen to move on the afterlife, but remained tethered by her love for Brainiac 5. Querl found a medium named Meander to serve as a host body for Nura, so that they could enjoy an date in the flesh. While inside Meander, Nura was without her powers and failed to "see" and attack from Princess Projectra. Projectra needed to eliminate Dream Girl in order to carry out a plot of vengeance against the Legion. She freed some of the baser aspects of Brainiac 5’s psyche, which manifested as demons that attacked Dream Girl. This, just as Querl proposed marriage to her. Nura survived but was left blind-in both sight and foresight. Querl encouraged her to enter the beyond, but she refused, agreeing to marry him instead.
Much later on, Querl was able to return Nura’s spirit to a clone of her body, as was the same for the “data” of the other Legionnaires after a dangerous mission in cyber-space, in which their bodies were badly damaged during an attack. Nura and Querl decided to go through with their Mundane-World nuptials shortly after.
Later on, they were both on watch of Super-Boy Prime, making sure that he did not run amuck and attempt to cross the multiverses to cause damage as he had done in the past. They also continued to be part of the Legion, in their role in defending the galaxy from any villains having a rotten day.
