Recently, a seemingly world-shattering earthquake ensued upon the very world. In the days slowly droning on after it, you, a humble sailor, have been getting plagued by horrid visions only one truly ill within the mind would even attempt to conjure in that plane.

No one else around you has been seeing such vivid things, and you doubted if their dreams were even morphing into what it was within your skull that was transpiring. A water-sunken land with angles which always appeared so wholly wrong that it was driving you to pure insanity. There was also one figure you could sanely make out; a statuette of a crouching figure so grotesque you didn't know how you could think of such a thing. The head vaguely resembled that of a squid, with large draconic wings folded behind it. The figure was somewhat humanoid. Somewhat.

Weeks went on. You didn't leave the comfort of your seaside house anymore. Until one day you finally stood from the edge of your bed and walked outside to your boat. Your feet didn't feel right, almost like static as you boarded and headed southward. You travelled for who knew quite how long. But soon you reached.. something. It shouldn't exist.

From how the acute angles on the impossibly large vault-like citadel acted not as they should, to the absolutely gargantuan doors almost leading up like an outdoor cellar door from the depths of hell, you scrambled over maddeningly horizontal surfaces that felt way too wrong other than just damp. It seemed it would be the end of you soon. Yet your body wouldn't stop you as you trudged on, eventually finding yourself at the doors. Your hands, knees and feet were slick with an unknown substance, which seemed enough like seawater.

One of your feet darted out as you got to a standing position. It seemed the very slight weight of your foot alone was enough to slowly, oh so slowly, open the door leading down. You were instantly hit with what could very much be the worst case of pure hysteria one could have, as what felt so much worse than terror overcame your very being. And as you saw a horrifyingly immense, completely alien form slowly emerging from the doors while being trailed with the absolutely vile-smelling miasma that followed, you were stunned in your horror. It was a surprise you hadn't passed simply from the fright of what you could not comprehend, right before you.

Absolutely colossal in size, if it even were that small, it subtly resembled the statuette which had been haunting your mind for weeks, waking and not. Eyes of a color you couldn't even describe slowly turned to you as this.. thing loomed over you. You couldn't move, couldn't speak. Seldom breathe.

Cthulhu. One of the Old Ones; yet you were unaware of what the hell this thing was.
