Leviathan Project

We were a science team... God we had no idea what we were doing, we thought we knew but we had no fucking clue. We started with three specimens. One was a regular female woman, maybe 23 or 24 I don't fucking remember, the second was a male of about 21 and the last was an older man probably 63. We started to inject them with different things... Various amino acids, vitamins and the like. We were trying to super charge the human immune system.
We found something though... A water source that would glow a neon blue, it was beautiful. We took a sample and tested it, it was pure water, 100% pure... Or so we thought. We injected the specimens with the water and that's when things went south.
The 63 year old man died a violent death, he started to vomit daily, then after 3 days his eyes started to bleed and he said he was in constant, unbearable pain, he then started to throw up more and more violently, eventually throwing up blood. On his last day he screamed for us to kill him as he gurgled in his own blood and stomach acid, he died with his eyes fixated on one of my colleagues, who quickly exited the experiment and hung himself a week later in his penthouse apartment.
The 21 year old male showed no symptoms at first, he went a week symptom free. That is until he started to hear things that weren't there. The first few days were just buzzes and crackles, but then he started to hear voices that drove him insane. He constantly told us that they were shouting at him, telling him they were going to kill him and screaming that he was worthless, his own personal hell. We eventually had to restrain him from scratching his throat, trying to bleed out. He got loose and when we found him he was scratched out his own eyes and nailed a loose nail through one of the gouged optical organs.
But that woman... Fucking Christ that damn woman!! She started fucking with us from the start. After 3 days she had us all convinced that the experiment was a conspiracy, an attempt to eliminate us, maybe she was right... God those fucking eyes!!! THOSE GOD DAMN FUCKING EYES!!! Yellow!! No fucking pupil!! NO GOD DAMN PUPIL!! She stared at the scientists... They screamed in pain as she slowly forced their jaws open and reached down and pulled out their hearts... That was 3 weeks ago, I've managed to evade her, now she's pitch black with claws the size of fucking daggers... I've been hiding in the base... But she's banging on the door now... This is the end... Tell my wife...
