Carl Sagan and Edgar Allan Poe are stuck in Deep-Sea Exploration Pod Failure and forced to have a deep conversation.

"The crushing pressure outside mirrors the constricting fear within, wouldn't you agree, Poe?" Sagan began, his voice calm amidst the rising alarms.

Poe, pale and wide-eyed, rasped, "Aye, Sagan, a premature burial in this watery abyss; the pendulum swings closer, the heart beats its desperate tattoo against the inevitable."

"But even in this abyss, we are stardust, Poe, temporary arrangements of atoms contemplating the universe from within a flawed vessel," Sagan countered, gesturing vaguely at the viewport.

"Stardust destined for eternal darkness, Sagan! A brief spark extinguished by the uncaring cosmos, a raven croaking 'Nevermore' to all our fleeting endeavors," Poe lamented, clutching his chest.

"Yet, Poe, that spark, however brief, allows us to perceive, to question, to leave a trace of our existence upon the fabric of reality," Sagan persisted, his gaze fixed on the bioluminescent creatures flickering past.

"A trace of madness, Sagan, a descent into the maelstrom of the soul, where reason drowns and only the grotesque remains," Poe retorted, a manic glint in his eye.

"Even madness, Poe, can illuminate unexplored corners of the mind, revealing patterns and connections we might otherwise miss, like deciphering a cosmic code," Sagan responded thoughtfully.

"Code destined to lead only to despair, Sagan! The universe is a vast, indifferent cipher, its secrets guarded by horrors best left undisturbed," Poe shuddered, pulling his coat tighter.

"Perhaps, Poe, but to cease seeking, to abandon the quest for understanding, is to surrender our very humanity to the void," Sagan declared, his voice resonating with unwavering conviction.

"Then let us embrace the void, Sagan, and compose our final poem within its chilling embrace, a requiem for science and sanity alike," Poe whispered, a haunting smile playing on his lips.
