little is known before he joined the Cleansed, stationed on a U.N.S.C colony that was mostly remote and kept secret by oni. they did tests of the flood to see if they can be used against the covenant during the human covenant war, sense the world was mostly inhabitable and marked as a necessary, there was small outposts and settlements in witch Nemesis and his team Nightmar was tasked with monitoring the experiments, and containment. the population was mostly just miners and farmers. they would bring pow's from the war, but Nemesis would see that some are alien and human, the races with a common fate in the name of science. ships filled with these pow's would drop off more subjects and leave, tho with all these experiments oni learned nothing of use. the infected pow's would behave like feral beasts and attack any one they saw and they would get casualties. little do they know that people who were cut or even had flood blood spilt on them they would succumb to the infection. and the med bay was quickly over run, the regular solders would be killed trying to contain the outbrake, Team nightmar was sent to eliminate every one in the facility. and as they did so they learned that the infection can use guns and after some time there attacks were more strategic. the station was put in lock down trapping the spartans and flood, they relied on the Spartans to contain the infection, but as they kill there way into the hive one member was injured when a flood carrier exploded near them, as the facility's walls are Closter phobic and easy to be ambushed. aswell as the near endless waves of former friends and solders. in the chaos there Team mate turned and struck another member, the combat form hit the spartan so hard it shattered the armor on the abdomen, shortly Nemisis saw this and shot his infected Team mate as it rips apart one of there Team mates it seemed to have little affect and him and the remaining Team members tried to radio in for extraction, oni marked them as a loss and they had to fight there way into the control room to find a way out, they were left on there own but they had not intention to join this collection of flesh and they decided to fight there way into the armory and attempt to blow the whole station up. as they foght there way into the armory only Nemisis was able to make it as he carried the tags of the comrade he had to kill. in his eyes they were no longer the friends he knew and are monsters to be destroyed, the station he survived the exposition by using one of the lab rooms that was ment to see how the infection reacted to explosions. tho the station was obliterated he fond himself in a capsule, turns out he was in a Pelican Troop bay, it was dark and ominous. he tryed to call out to see if any one was around, tho he got no replies he looks at the walls in the dim light of the troop bay of the pelican and notice some bloody hand smears and knew his situation, he quickly smashed his way out the capsule, soon he was ambushed by what used to be the pilot, he ripped its web hand off and impaled it with its own arm, he looks into the cock pit to see if there was power to the craft, tho it would be to easy if the pelican was working, it turns out it was in mid refueling process. so he opened the hatch to the troop bay and left into the darkness. when approaching to the control consul to finish the fueling process he though of who would even bother searching for im in good intentions as every thing at the station went to hell and his leaders left him to die, so as the refueling process began he went back into the pelican to find out were it was going and what ship he was on, as he did he locked the hatch behind him to search for answers, as he did he learned he was going to be taken to stasis and put on a p.o.w ship to have a fate like the others in that station, he thought to himself, all those people, his Team who died at the hands of the flood, what he clenched his fists and slammed against the wall next to the console in anger, tho he controlled himself not to smash the computer, then he leaves the pelican to finish the Refueling as it was complete, he then removed the smashed capsule, and and set up to leave. he opened the airlock and entered the pelican, normally he would be sucked into space but his boots had a gravity clamps that allowed him to walk back into the pelican and he left, unsure what to do next he just flew into the void, he was sure he was Dead already and at this point he didn't care about that and just wanted rest.
