Yalu (symbiont): Difference between revisions

The Trill are a humanoid species, of whom a small percentage co-exist with a sentient symbiotic organism, the symbiont.  The relationship between humanoid host and symbiont plays a significant role in Trill culture and spirituality.  Joined Trill have personalities which are a synthesis of the two beings, including the memories, skills, and personalities of the previous hosts.

While the Trill possess a similar average lifespan to Humans, Bajorans, and other Alpha Quadrant humanoid species, the symbionts are considerably longer-lived.  When the humanoid host dies, the symbiont is removed and joined to a new host, whose identity becomes merged with the symbiont and the preceding hosts.
