[you plunge, without warning, into water. it's pure and clear and refreshingly cold, a flurry of bubbles rising around you; you can breathe it, somehow, and move with ease. there's a distant beat at the edge of your hearing, a tidal pulse keeping time in this place.

which way do you choose to go?]
