The Zenith Alliance was a super-secret alliance of several different species, including Klingon, Cardassian, Gorn, Breen and even a few Humans who followed the teachings of Xolor, a sinister being with a lust for obtaining complete control over the galaxy.
The origins of the Zenith Alliance were shrouded in mystery, but according to Kardok, it had been gaining a following "in the shadows". Despite the fact that numerous species had members within the Alliance, the organization's existence was almost completely unknown.
While no governments were officially members of the Alliance, various species were represented within its ranks, including:
- Star Trek: Federation Legacy – "Zenith" (First appearance)
- Star Trek: Federation Legacy – "Zenith, Part II"
- Star Trek: Federation Legacy – "Zenith, Part III"
