The first story depicts alien beings engaged in strength-testing and combat preparation for inter-world conflict, with their civilization experiencing rapid acceleration of their young males' warlike development. The second story, "The Yodler of Yognasi," follows mountaineer Williard Merrit's attempt to climb Mount Sugarina, where he encounters the mythical Yodler—a creature whose horn-call creates landslides—and discovers it is actually a being from an alien civilization that arrived twenty-two cycles ago; the aliens have established a hidden city on the cosmic rays, don't eat or breathe like Earth people, and invite the climber to visit their manufactured world where they offer him freedom to come and go as he pleases.
Jo, a lone explorer, stumbles upon a hidden trove of galactic wealth on the dark side of the moon, only to be confronted by a figure from his past who reveals the moon’s true purpose as a high-security prison for the galaxy’s most dangerous minds. The man who once vanished now returns to reclaim Jo—not for revenge, but to ensure Earth’s first contact with alien civilizations remains untainted by greed.
Jo, a young man feeling stuck in life, sees a chance to finally break free from his self-perceived fate when he attempts a daring billiards shot—only to find his moment interrupted by a surreal cosmic revelation. Meanwhile, on a microscopic world shaped like a billiard table, tiny inhabitants face an existential threat as their planet’s "mountain" begins to move, mirroring Jed’s desperate struggle. The story unfolds with a quiet, ironic twist that recontextualizes both Jed’s personal frustration and the fate of an entire civilization.
In the wake of the Grand Canyon’s sudden disappearance, scientists from around the world converge on Colorado to investigate a mysterious, alien material that has filled the canyon and resists all known methods of penetration. As global tensions rise, a team of researchers discovers the material only allows light to pass through from below, hinting at a deeper, deliberate mystery.
When famed climber Williard Merrit sets out to conquer the legendary Mount Sugarina, his companion Frank Delaney grows uneasy—especially after hearing the eerie yodeling said to summon landslides. As Merrit and his team face terrifying rockfalls, Delaney races to uncover the truth behind the myth, only to find the danger isn’t supernatural, but rooted in a shocking, unintended consequence of human action.
In a whimsical twist, flea circus owner Karl Crowder insists his performing fleas have emotions and ambitions, sparking disbelief from a skeptical observer. As the two watch a tiny drama unfold—where a flea named Herman tries to impress Rosa by pulling a wagon, only to struggle until Felix’s hidden sabotage is revealed—the story blurs the line between imagination and observation, leaving the question of whether the fleas truly possess awareness hanging in the air.
