The eye itself had a rainbow iris and was covered in some sort of almost clear grey crystal.
Next to it, was a tiny piece of paper explaining how it worked. Apollo picked it up and read it.
'Unicorn eye. Used to gauge the purity of those it lays its eye upon. Holding it will let one see a living being's sins in the form of red light.'
Then, the paper disappeared.
Apollo looked at the unicorn eye for a moment before picking it up. Almost immediately, he saw thick and dense red tendrils of light coming off of his body. They were dark red, almost black.
Apollo smiled bitterly.
"It seems I'm not exactly the purest of people."
He brought the unicorn eye closer to himself, and looked at it. Almost immediately, the eye got a little bloodshot.
It was as though the eye hated to look at Apollo.
After a bit of hesitation, he decided to stick it into his pocket, causing those visions of the red tendrils to disappear.
