Far before the events of playable ONI, Gravitas was founded by Jacquelyn Stern, although there are no lore messages or implications that can be made dating back before the founding of Gravitas, aside from the fact that the game takes place in the 23rd or 24th century. Keep in mind that every character mentioned in this project with the exception of Jacquelyn can be printed as a duplicant. Gravitas, soon after founding, eventually rose to popularity (although a very questionable rise, as hinted by one of the lore messages), although I highly suspect the temporal bow (more on that later) likely had something to do with this. Sometime around after Gravitas got an influx of new employees straight from school, the facility was stealing DNA to use for the printing pod, which had a major set of problems at the time. While Dr. Jones (or, from what I have inferred, Ellie Jones) had solved the weight issue from taking the printing pod to space, the machine required massive amounts of power to run. In a later (or previous, I haven't set the timeline yet) conversation with Olivia (or Dr. Broussard), Jackie mentions that they have another option to solve the weight and power problem of the printing pod, using 'redacted' technology (which I suspect has to do something with the temporal bow). Olivia also notes that Jackie is eager to move past important stages in creating the printing pod, which concerns her. There's also another log by Olivia concerning Jackie and how unethical their teleportation experiments are, however, it's important to note that instead of their ID being B111, it is B111-1, which I suspect means that they were either teleported OR it's a dupe of Olivia. Another thing to note is that Olivia and Jackie were the ones who started up the temporal bow, although soon after Olivia realized that it was producing Neutronium. Olivia brought her concerns to Jackie, only to have it fall on deaf ears. It's important to note that Neutronium is a man-made element, as one of the printing pod's log entries suggest. That's all of the lore I have for now, but more will be added for sure
This is all just some theories on the lore of ONI.
