Sequanis

Sequanis is a fictional planet featured in the science fiction novel "A Fire Upon the Deep" by Vernor Vinge. It is a world inhabited by the Tines, a species of intelligent, pack-minded beings who exist as multi-bodied organisms. Each Tine is composed of a group of five dog-like animals that are symbiotically linked, with each individual animal possessing a limited degree of sentience and the collective forming a single, complex consciousness. This unique biology is central to their society and their interactions with other species.

The Tines of Sequanis are known for their intricate social structures and their deep-seated rivalry between different packs, often referred to as "clans." These clans are constantly engaged in complex political maneuvering, warfare, and philosophical debates. Their communication is nuanced, relying not only on vocalizations but also on body language and the intricate interplay of the individual members within a Tine. The planet itself is depicted as a harsh but beautiful world, supporting the Tines' unique way of life. Sequanis serves as a significant setting for the novel, providing a backdrop for the exploration of themes related to intelligence, consciousness, and interspecies relations. The Tines' distinct nature makes them a memorable element of Vinge's expansive literary universe.
