A nap and some yardwork later, I had an idea. It's been growing since.
Feedback appreciated.
It was not easy to leave Terra. She was old, sucked dry of natural resources, crumbling under the weight of our teeming billons, slowly collapsing into entropy.
But space was worse. The first three colonies on Luna died without ever sending a message back: we still don't know what happened. When an oxygen tank ruptured on the first L5 habitat it spiraled down into the atmosphere as a 5000 km streak of flame: the inhabitants evacuated, then chose suicide when they realized we had no way to rescue them.
We clawed our way out of the gravity well on the corpses of five billion men, women, and children, brave pioneers all. We succeeded in establishing our civilization across the solar system with iron discipline and the guidance of those who came before us.
We regulated our waking and sleeping, we rationed our food. We rigidly controlled our births and our deaths so as not to outgrow our food, water, and air. We recycled our industrial waste, our excrement, and even our own corpses and cognition.
And today, all that ends. Today, the tesseract drive gives humanity the bounty of the universe!

The year is 3572. The tesseract drive has not given humanity the bounty of the universe.
The Emperor, advised by the downloaded consciousnesses of his predecessors, has sent out explorers in tesseract drive ships. The reports for these expeditions are slow in returning, and must be carefully considered before any ill-advised actions are taken. Some day it will be safe for civilization to explore the universe.
For some people, some day is right now.
Stripped of all flavor text, a society facing extreme hardship survived only by taking the most draconian of measures. People do need licenses to have children. The police take you away when you are seventy or so, download your consciousness into a weak artifical intelligence, and then humanely euthanatize you before composting your corpse. Food and water are rationed. There are sumptuary laws. There are police looking for dissenters -- if they find you, you go on the compost heap without benefit of download.
People live in space stations and pressure domes: despite everyone's best efforts, terraforming just doesn't work in the field.
The tesseract drive was supposed to change all that by effectively allowing faster-than-light travel: the mathematics to design the drive are fiendishly complex, but once the design was complete, it was easy to make with current technology. Private citizens could build one if they could do the design work.
Official Imperial exploration vessels have been built and sent out. None have returned yet, and some people are getting impatient. They're willing to fight for their freedom -- with their bare hands if they have to. Given the tight control of their society, they usually have to.
Points to Ponder
1. Is the Empire evil? Are they suppressing the tesseract drive and faking the exploration voyages? Maybe it's all a scam...feed the people false hope to keep them quiet...
2. Has the Empire been outmoded? The tight controls necessary for survival have left the empire very conservative. This conservatism gets reinforced if you add ancestor worship and downloaded consciousnesses as weak AI's. The weak AI's cannot learn new things, only repeat previous responses to stimuli. They can't handle the newness of the tesseract drive. The Emperor might be in a tight spot too. For years they've taken counsel with the greatest political, military, or legal minds of the past: it's like becoming President of the US and having Thomas Jefferson, George Washington, Abe Lincoln, and FDR around to offer you advice. Would you be willing to disagree with Abe Lincoln?
3. Is the tesseract drive safe? Maybe monsters live inside the tesseract: when you go inside Tzeentch comes and eats the ship. Maybe Tzeentch does something else you don't find out about until the ship comes back crewed by warp zombies.
