Revision 1

The rain of thought is a concept in Varsapura's worldbuilding that explains the supernatural nature of the City of Rain's perpetual downpour. In this world, humanity's collective unconscious (the shared psychic layer of fears, memories, and emotions beneath normal awareness) manifests as actual rain. The city's constant rainfall is not a meteorological phenomenon; it is the visible expression of billions of human thoughts and feelings draining from the collective psyche.

How it works

The basic mechanism is this: humanity generates a constant stream of thoughts, emotions, and unconscious impulses. In Varsapura's reality, this psychic output drains downward through the consciousness space and manifests in the physical world as rainfall. Under normal conditions, this process is stable. The rain falls, the city stays wet, and life continues. The population has adapted to living under perpetual rain, treating it as their normal weather.

Improper drainage and Mindrot

Problems arise when the rain of thought "drains improperly." The exact conditions that cause improper drainage have not been fully specified, but the result is Mindrot: a dark, tar-like substance that pools in the physical world. Mindrot is, in effect, stagnant thought. It collects like standing water after a flood, except instead of clean water it is a psychically charged corruption that spawns shadow monsters and causes Cognosea disruption events.

The analogy is straightforward. Think of the collective unconscious as a drainage system. When it flows properly, the rain of thought washes through harmlessly. When pipes clog, the backed-up runoff becomes toxic. SEAL agents are, in this metaphor, the maintenance crew dispatched to clear the blockage and deal with the contamination.

Thematic roots

The rain of thought draws directly from Carl Jung's theory of the collective unconscious. Jung proposed that all humans share an unconscious psychic layer containing archetypes (universal patterns of thought and behavior). Varsapura takes this abstract idea and makes it concrete: the collective unconscious is real, it generates measurable output (rain), and when that output goes wrong, it causes tangible danger (Mindrot, shadow creatures, dimensional instability).

The choice to use rain as the physical expression is fitting for the Singapore-inspired setting. Singapore has a tropical monsoon climate with frequent heavy rainfall. Varsapura recontextualizes this familiar weather pattern as something supernatural, turning a mundane feature of Southeast Asian life into the foundation of the game's mythology.

Narrative implications

If the rain is generated by collective human thought, then the nature of the rain (and by extension, the severity of Mindrot outbreaks) might change based on the population's psychological state. Periods of collective anxiety, grief, or fear could theoretically produce more dangerous rainfall and more frequent Cognosea events. The game has not confirmed this dynamic, but the logical framework supports it.

This also raises questions about whether individual characters' psychological states affect the supernatural environment around them. The Hollowone protagonist's personal trauma (the destruction of her "former self") could make her a lightning rod for Mindrot activity. The inner world mechanic may explore this connection between individual psychology and the broader supernatural system.
