Even though she was a math and military major she had to take a bunch of non-degree related classes. She learned about the Earth empire and its fall after the war with the second alien interstellar species that humans had come across. Earth had been a battleground for many years as both species fought over the planet with the humans finally winning. The butcher bill for the planet was steep with many of Earth's old colonies paying the steep price while the rich citizens of Earth hid out in server farms safe in their digital world.

Because the horrors of what the soldiers were exposed to, laws were made so that digital soldiers had rights that no one could take away.
