the project was made to make the mass death of enemies mainly civilians on lone worlds easier. using what is called a "monolith" The monolith transmits a signal that makes civilians insane and causes them to have hallucinations that everyone around them is their enemy and are compelled heavily to kill as many people as possible. it then uses a robust electromagnetic signal to transmit the tissue of a dead person on the molecular level to reanimate. these specimens are called "mortui". then resurrected body cells would go into overdrive to grow the body bigger and deadlier. the "mortui" then starts attacking any nearby living people. the mutations vary depending on what the monolith "needs" as in if the enemy is using guns to kill you make armored or if ships are in orbit a giant biomass tentacle thing will attack them pulling them to the ground and absorbing all the boi mass of the crew. the bodies then become deformed, bloodied, and yellow sacks bro around the body which store energy for hibernation. they have no repository system so they can survive in the vacuum of space on top of that they can only be killed with heavy blood loss and since they don't have organs they bleed easily. After as much bio-mass on the planet is harvested the mortui meet at the location where they all come from. then they coalesce into one body which leaves the planet and if the planet has moons attach to the moon and lay dormant. these are called "ancients" since they can live for over an estimated 40 million years. these would then see fit if monoliths should activate and at what time. only 4 monoliths have been made so far so more are going to be made.
