...This has been the worst adventure ever.

Not only were you lost in the weird mineshaft under Cabin Fever Labs, having gotten separated and left alone with Tessa, but now Tessa herself was also gone after the power fluctuated suddenly. The dark corridors of the strange old mines made it impossible to see anything properly, only barely lit by the occasional dim light lining the various turning paths.

This was just great. Nobody around, no knowing where to go, and now you were just going to have to hope you didn't run into anything bad down h—

[I see you.]

...At the end of the corridor ahead of you, a singular light flickered faintly. The dim fluorescence made it nearly impossible to perceive anything, but it was enough to make a general spot of light. Just beyond it, what looked like two small neon-yellow Xs flickered slightly, like a pair of eyes that were watching you.

The light flickered out for a moment, the corridor growing deadly quiet...

And just as suddenly, the light came back. It illuminated a humanoid shape stood there in the light, hunched over awkwardly with various tendrils poking free from its back, appearing as still as a statue as it stood there in the light. You couldn't make out it's face, the shadow of the dim light above making it impossible to perceive any proper features. Those dim neon-yellow Xs stared silently, before the light went out again.

...And when it turned back on, the figure was nowhere to be found.

Well, that isn't terrifying at all.
