[X] Warp Interdiction: It has been discovered that sufficiently intense gravity waves can disrupt the functioning of a warp drive and force the offending ship to drop to sublight speeds. Even better, by alternating between attraction and repulsion, the overall movement of nearby objects can remain mostly unaffected.
[X] Bio-Genesis: It is now possible to create new biological lifeforms from scratch without pre-existing lifeforms to modify. This could even allow the humans to be re-created, though they really wouldn't be the same people who gave you life.
[X] Generous: Giving back to your community has always been an important part of the Newman psychological makeup, even before they were sapient. This tendency has come even further to the fore in recent years, with almost any Newman with surplus resources expending a significant portion of them to aid the less fortunate.
[X] Comm Holes: Further developments based on the QDC allowed for the production of traversable wormholes the size of a pinhead. These wormholes were still small, but they were perfect for interstellar data transmission, lacking th major weakness of QDCs.
[X] Guardians: Knowledge of what the Missionaries had done, and their new capabilities to prevent such a tragedy from occurring again produced a determined resolve among the Newmen. The universe may be dark and full of terrors, but the Republic would not let them bring their evil to the innocent again over their shattered wrecks. Never again would the innocent quiver in fear.
[X] Basic Nanites: While not much more capable than a mechanical microbe, these devices are nonetheless incredibly useful for assembling very complex molecules in an efficient manner, easing certain manufacturing processes. They also allow for Newmen to heal without external repairs, though it's still something that can take weeks.
[X] Moderated Expansion: While rapid expansion is desirable, it is wise to do so in a controlled fashion. Overextension has been the death of many an empire.
[X] Shielding: One of the things that gave you the most trouble taking down the Missionary mothership was its defensive shield, composed of a layer of low-temperature plasma confined with an intense electromagnetic field which could quite handily block most of your weaponry. You have replicated this technology.
[X] Basic Megastructures: With the new hyper-durable alloys and improved manufacturing techniques, it has become possible to build structures on the scale of thousands of kilometers, for purposes ranging from habitation to warfare. Even better, courtesy of gravity drives and warp, these structures can be mobile.
[X] Improved Nuclear Fusion: While practical fusion devices had been in use prior to the Missionary invasion, the Missionaries had reactors and torch engines an order of magnitude better than what humanity could muster by every metric. You have managed to fully recreate this level of performance, and even improve on it.
[X] Total Security: The only ones who should pilot warp ships are those specifically built for the job. Only those rigorously engineered and tested for trustworthiness and stability can be allowed anywhere near the controls of a warp-capable vessel.
[X] Ship Design: Much was learned from studying the Missionary's ship. Putting these lessons to use when designing our own space vessels in future will greatly aid us when it comes to making our ships more durable, faster, and overall better.
[X] Nostalgic: The formation of the Church of the Reborn was only the beginning, as a new wave of grief and sadness regarding the loss of the humans washed over the Newmen. Thus, attempts to recover as much of human culture from before the invasion as possible continued apace, bringing with it a resurgence in human pop-culture from before the invasion.
[X] Improved Laser Weapons: Optimal for long-range space combat, you have improved the output of your typical X-Ray lasers, enabling you to severely put the hurt on your enemies in space combat.
[X][2] Shielding: One of the things that gave you the most trouble taking down the Missionary mothership was its defensive shield, composed of a layer of low-temperature plasma confined with an intense electromagnetic field which could quite handily block most of your weaponry. You have replicated this technology.
[X] Blunt: There was no sense in deluding oneself about what was going on. While indirect talk had never been popular before, not getting right to the point was now seen as a sign of weakness in one's position in a debate, to the point where such misdirection and allusions almost vanished in their entirety.
[X] The Conservative Approach: No sense in pushing yourself too hard and fast. It's best to thoroughly develop each system you claim before moving on to the next ones, so as to maintain a general sense of national cohesion.
[X] State-Run: Private individuals and organizations cannot be trusted. Only those working for the government, where they can constantly be monitored, can be trusted.
[X] Artistic: During the early phases of interstellar expansion, the arts surged into prominence. Filmmaking, abstract painting, even cooking among Revivalists were all common pastimes, with the true masters adding to the Newmen's cultural heritage in ways that would last as long as the Newmen themselves.
[X][2] Improved Laser Weapons: Optimal for long-range space combat, you have improved the output of your typical X-Ray lasers, enabling you to severely put the hurt on your enemies in space combat.
