Trill: Unjoined, by writing duo Michael A. Martin and Andy Mangels, is the first story in the second volume of Worlds of Deep Space Nine, part of the Deep Space Nine Relaunch.
Within every federation and every empire, behind every hero and every villain, there are the worlds that define them. In the aftermath of Unity and in the daring tradition of Spock's World, The Final Reflection, and A Stitch in Time, the civilizations most closely tied to Star Trek: Deep Space Nine can now be experienced as never before...in tales both sweeping and intimate, reflective and prophetic, eerily familiar and utterly alien.
TRILL: They are a people with secrets. For centuries they kept their true nature hidden, even taking disturbing steps to protect the small population of near-immortal symbionts with whom a privileged few Trill are joined, body, mind, and soul. They are a people who hold memory to be sacred, yet deny their own past. Now amid a whirlwind of scandal, accusations, and growing civil unrest, Ezri Dax must penetrate millennia of lies and deceptions, and rediscover what should never have been forgotten, before her civilization rips itself apart.
