The following account was recorded in the agent's log during your transmission: Ancient, twisted mangroves writhe from the depths of a dense, perpetual twilight, their gnarled branches like grasping fingers shrouding a colossal, forgotten gateway in shadows. Umm, the air's heavy with salt and decaying plant matter, a faint tang of ozone riding the slow, damp breeze like a warning. Through the entrance, an unearthly silence pours, seeming to stem from an endless, inverted cathedral made of crystalline formations, their refracted light imbuing everything with an eerie, pearly glow, and from somewhere within that abyssal space, a lone, colossal, pendulous voice thrums in beat with my own heart.
