Imperishable Memory

The Empire never leaves those fallen in battle behind. Unfortunately, not a single defender has survived to give their fellow soldiers a decent burial... That's not fair! We must know the names of the heroes who gave up their lives in the name of scientific progress!
Please, find the tokens of the diseased soldiers. When we get out of here, I will send them to the Imperial Keepers.

As Nezeb said: "The one who does not have respect for the past, does not have the future!"

What kind of science demands human sacrifice?
