Baraj'aran was a Jem'Hadar First during the Dominion War.

In 2373, Baraj'aran and his troops were sent to establish a communications base on the planet Illarh under the command of the Vorta Sejeel. The Illarhi allowed the occupation without any resistance. Some time later Starfleet forces under Jean-Luc Picard liberated the planet from the Jem'Hadar. (STA short story: "What Dreams May Come")
