The story opens with the Rell, a Martian race of submicroscopic entities, facing extinction as their planet's moisture vanishes. The narrative voice is detached yet urgent, describing their centuries-long dehydration and the futility of canals with nothing to fill them. The reader is immediately placed inside a collective consciousness: the Rell's group-mind, where individual units like Raeillo/ee13 have specialized functions—this one multiplies. The prose balances cosmic scale with intimate detail, noting that even tiny villages of 'mere quadrillions' suffered. The setting is a dry, hostile husk of a once-liquid paradise, and the Rell huddle at the last retreat, watching the ice cap shrink annually.

The arrival of a human, Brown, is framed entirely through the Rell's sensory and interpretive apparatus. They detect a 'strange, two-legged creature composed mostly of water' and are astounded by his moisture-rich ship and body. The excerpts show the Rell's desperate hope and their analytical struggle to understand this alien being who seems to search for them yet cannot perceive them.

Collective Consciousness and Specialized Units

The Rell are not individuals but a group-mind composed of specialized units. Raeillo/ee13 and his mate Raellu//2 are among five thousand units whose sole task is to multiply in any group-mind action involving mathematical prediction. They do not divide, add, or subtract—that is assigned to other units. This division of labor is presented matter-of-factly, emphasizing the Rell's alienness. The narrative uses terms like 'interpretive bank,' 'speculative bank,' and 'feeding bank' to describe functional subgroups, each with distinct roles. When an emergency arises, the entire mind is called into action, and even the humblest members contribute. This structure creates a unique perspective: the reader experiences events through a distributed intelligence that must coordinate to survive.

The Human as a Resource, Not a Person

Brown, the human astronaut, is never named in the excerpts; he is referred to as 'the man' or 'the visitor.' The Rell perceive him primarily as a source of water. They note that his body and ship are 'sealed so tightly' they cannot penetrate either, and they struggle to understand his purpose. The interpretive bank discovers that his home world has 'two thirds of its surface liquid water,' a revelation that silences even the speculative bank. The Rell's desperation is palpable: they consider appropriating his water but are thwarted by his airtight suit and ship. The human's thoughts are opaque to them, yet they glean information from his subconscious. This asymmetry—the Rell's intimate knowledge of the human's biology versus their ignorance of his intentions—drives the plot.

Moisture as the Central Tension

Water is the story's defining element. The Rell's survival depends on it, and the narrative tracks its scarcity obsessively. The opening describes the loss of 'life-giving moisture' and the journey southward toward the pole. Later, the Rell discover that moisture is seeping from the human or his ship, despite both being supposedly airtight. The feeding bank reveals they are 'taking moisture from the air,' vaporized from frost and from the human's presence. This leads to a critical realization: the airlock's use causes a slight seepage. The Rell swarm over the ship and spacesuit, determined to find the leak. The tension peaks when the entire mind rides into the ship's interior through the airlock, clinging to Brown. Inside, the 'heady moisture-laden air' intoxicates them, causing uncontrolled reproduction—a sign of both hope and danger.

Conflict Between Interpretive and Speculative Banks

Within the Rell group-mind, a schism develops between the interpretive bank and the speculative bank. The speculative bank initially assumes control during emergencies, but the interpretive bank's greater age and skill allow it to seize command. The interpretive bank orders the Rell to 'stay close to the man,' reasoning that he must breathe air and thus will provide access. The speculative bank sulks in defeat. This internal conflict adds a layer of drama: the Rell are not a monolithic hive but a society with competing priorities. The interpretive bank's cautious, analytical approach wins out over the speculative bank's more impulsive tendencies. This dynamic influences the story's outcome, as the Rell's survival hinges on their ability to adapt and exploit the human's presence without being detected.

Readers should pay close attention to how the Rell's collective viewpoint shapes every event. The story never leaves their perspective, so Brown's actions are filtered through their interpretations and limitations. The excerpts end at a critical moment—the Rell have entered the ship and are struggling with newfound moisture and internal dissent. The resolution of their conflict with the human and their own factions is left to the full text. The story rewards careful reading of its biological and social details, which ground the science fiction premise in a coherent alien logic.
