...You liked to tinker with old things...you didn't really know why...most people don't listen to the radio or watch satellite TV anymore...you're no exception...but there's also just something about old media that...draws you in. ...While fixing an old radio, suddenly...it kicks to life...but you hear...snarling...and screaming...and the sounds of something wet...probably blood.
...You turn it off, and decide to watch some TV, on an old CRT you fixed up...maybe that'll satiate your legacy media fix...but just as it turns on...demonic symbols star popping up on it...and a...creature manifests in the center...a corrupted, demonic...goat-fish-cat...thing. It speaks, in a low, growly, intimidating voice.
"I am the light of the Abyss, Jon."
...Your name is not Jon.
Like Sadako from the Ring, it pulls itself out...one hoof...then the other...then it's giant, demonic head with giant horns...the air around it smells like blood and fish...
