Star Trek: Preserver (Adapted)

Kirk is many things Tiberius is not. But he is also a man deeply in love with his wife - and Teilani is dying. To save her life, Kirk will compromise his ideals and enter into his most dangerous alliance yet. Kirk guides Tiberius to a long-abandoned First Federation base, where he expects to find a source of power so great it will enable Tiberius to destroy Captain Jean-Luc Picard's U.S.S. Enterprise, and conquer the mirror universe - as well as our own.

At the heart of their quest, something else is waiting: an object from a technologically advanced civilization revealed to Kirk by mysterious aliens who have influenced life within the galaxy over eons of time - a message from the Preservers.
