Levi had probably been down in this forgotten underground bunk a dozen times. Each time he'd find something different.
The first time he'd found a couple of old, moldy notebooks. Moisture and time had made them brittle and unreadable. When he tried to turn a page, it would completely fall apart.
The second time he went in, he went further into the compound and found old electrical equipment that could have belonged to Faraday or Tesla. He tried a few switches and levers to see if he could get anything to happen. So far he hadn't had any success.
On his last trip he'd found a rather large room that was filled with odd designs and writing on the walls. He couldn't make heads or tails of what he was seeing. For some reason he felt the light that he had wasn't quite right. Maybe a different color might help.
Now he was standing there with a black light flashlight. The UV light made images on the walls stand out.
Images that he wishes he'd never seen. Images reminiscent of Lovecraft's "Pickman's Model."
They seemed to depict an other-worldly demon's conquest of the denizens of this bunker.
His hair stood up in his terror.
He was turning to flee when he heard something scrape the floor behind him.
