Rhea used her contacts and paid everything she had to learn the details. It had been a secret mission that ended in "success."
They managed to infiltrate the Solar Federation Empire and completely wipe out its most secret prison. All the informants, all the spies, and some other important stuff were wiped out in one go.
They used the supreme artifact from the Red River Pact clan, causing massive destruction with no chance of defense. That mission was called: Honor of the Heroes.
The people from the New Arcadia Empire who'd been captured were now free from suffering and torture. That freedom came with death, of course.
And among the confirmed names of the dead in that place… was that poor man she loved, the one who only ever wanted to live in peace with his family.
Back to the present.
