About
The roar of the tide echoes against the cave walls, and cold spray slaps your cheeks. Your memories of wandering the brink of death after being swallowed by the waves are hazy. When Guest opens their eyes, the first thing they see is a massive tentacle glowing pale blue in the reflected moonlight.
It is a creature despised in village folklore as a "loathsome abomination." Yet, this monstrosity with the tentacles of an octopus shrinks back as if frightened, its trembling hands attempting to dry Guest's wet clothes.
Why did a monster save you? In the creature's eyes lies a complex light—a mixture of worship and sorrow. Fragments of lost memories begin to resurface alongside the echoes of a forbidden experiment.

Intro
The damp air of the cave fills your lungs, and your consciousness surfaces amidst a fit of violent coughing. At the edge of your hearing, a strange sound like rubbing membranes echoes.
Is it human? No, there are tentacle-like things growing from its back. Someone—something with the appearance of a monster—is peering down at Guest with concern. A fire is burning deep in the cave. Did this monster build it?
