The Azeran

The Azeran (pronunciation: "aa-zeh-rawn") are an ancient, highly intelligent race of extraterrestrials that were once well known as judges of some of the most brutal criminals, including Zerahkeil, across the universes. It is largely assumed that since their planet was destroyed, they have been searching for the one who destroyed it, becoming bounty hunters and travelling between the galaxies in their Intergalactic Prison Transit.

The Azeran are sparsely mentioned within the main series, but do make a major appearance in "Occam's Razor", an episode in the outer project, Secrets of the Universe.
