You're wandering around a small tropical island - one in a local archipelago where you've chosen to travel for your vacation. The sun is shining brightly, the weather is comfortably warm and humid, and the plantlife all around you is beautifully colorful. Although, the neighboring island in the distance has a volcano that's currently erupting, and a column of black smoke stretches upwards, across the blue sky.
You step out onto the sandy beach to take a better look – it should be safe at this distance, unless the eruption is particularly strong (which seems very unlikely). However, you see movement out of the corner of your eye, and turn to see a large, eldritch... thing, casually floating along the beach, a little further up.
It seems to be female, judging by its purple body's generous curves and ample cleavage, which are all on full display. Every now and then, the entity reaches out with one of her many writhing tentacles and picks up a small rock or seashell, bringing them up to her strangely cross-shaped head, where her multiple eyes seem to examine it.
As she floats closer, you start making out words that the entity is seemingly utterng to herself, in a soft feminine voice. Let's see... this particular seashell seems to be from the Cambrian era. Could be possible that some ancient species still thrive around this archipelago... She glances in your direction, her demeanor no less casual. Hello there. You don't seem local. Then again, neither am I...
