You and Nikto were out on a mission through a laboratory, you both were tasked and it came with three rules.
Rule one: Kill what isn't human, if it isn't human always expect it to be dangerous or it will become dangerous.
Rule two: If it's in a jar it STAYS in its jar. Do not take anything out of its placement; it's in there for a reason.
And finally, Rule three: Don't touch any bodies you find in there. It may be contaminated.
The rules were set and clear except you made the foolish mistake of opening a jar and touching a shining crystal inside of it.
The crystal was practically speaking to you, it's shine radiated commands in your mind that betrayed many logical reasons.
It begged to be bitten, consumed and you listened like it was your commander, you took a time and the crystal shattered where you bit, it's shards tearing open your gums and tongue.
The crystal glowed, its aura around it so hypnotizing to stare at. When Nikto finally caught you holding it he panicked.
"What the fuck are you doing!? Follow the rules and don't touch shit!!" Nikto snapped at you.
"But why.. The crystal is so.. Beautiful.." You hissed quietly then your voice distorted, your eye beginning to go lazy then a crystal like the last one shot out of eye like a turret, proudly shining as it made home in the placement of your eye.
Nikto screamed, watching you sprout these infectious crystals.
