jossilloin

Jossilloin is a fictional planet featured in the science fiction novel "A Fire Upon the Deep" by Vernor Vinge. The planet is notable for its unique biosphere and its role in the overarching narrative of the novel. Jossilloin is located in the "Beyond" region of the galaxy, a zone where the laws of physics are different and more complex than in the "Galactic Core." This distinct environment has led to the evolution of unusual and often dangerous life forms.

The indigenous inhabitants of Jossilloin, known as the Tines, are a fascinating species. They are pack-minded, with each individual Tine being relatively unintelligent. However, when Tines gather in groups of four or more, they form a collective consciousness that grants them remarkable intelligence and problem-solving abilities. This unusual social structure is central to their survival and their interactions with other species.

The planet itself is described as having a harsh and unpredictable climate, which has further shaped the evolution of its inhabitants and ecosystem. Jossilloin serves as a key location for several pivotal events in "A Fire Upon the Deep," including the discovery of ancient alien artifacts and critical encounters between the novel's protagonists and antagonists. The planet's unique characteristics and its Tine population are integral to the exploration of Vinge's complex galactic civilization and the nature of intelligence.
