A test subject was injected with demonic DNA

Day 35:
The war against the Forces of Light is difficult, our people are too weak to fight in these conditions. We need something more powerful.

Day 40:
Our scientists have detected abnormal activity in one of the underground laboratories, we are investigating.
What?! Are you crazy?! We can't do that! That thing is beyond our knowledge!

Day 42:
My partner said that this activity is probably demonic, it seems crazy, but we don't know.
We are thinking of using rare energy to create a space-time fissure.

Day 45:
We did it, the space-time fissure is now open, but I have a bad feeling about this.

Day 50:
As my partner said, the energy was demonic, the corpse of a strange creature came out of the portal, we are studying it.

Day 51:
We extracted the blood and DNA from the creature and discovered that they have amazing properties, we are planning to incubate more of these creatures and test their DNA on some of our members.

Day 55:
The creatures are growing well and it seems that the test subject is compatible with DNA, but shows signs of mutation in the head.

Day 60:
WARNING! ... WARNING! ... EVACUATE THE PLACE NOW!
NO! the subject and creatures have not fully developed!... wait, what?... AAHHH!
