Background
Macet was the cousin of Skrain Dukat and shared a striking resemblance with him that caused many Bajorans and those familiar with Dukat to distrust Macet, however that mistrust was generally put aside when such individuals got to know him and learned he was a very different man.

2360s
In response to the destruction of a Cardassian outpost by the Federation starship USS Phoenix in 2367, Macet ordered his ship to attack the USS Enterprise-D. However, his ship proved no match for the Galaxy-class Enterprise, and he agreed to a truce after his ship was disabled. Macet cooperated with Enterprise Captain Jean-Luc Picard in tracking down the Phoenix, which was believed to have gone rogue under orders from Captain Benjamin Maxwell. Macet brought two officers with him, Glinns Daro and Telle. In the interests of peaceful cooperation following the recently signed treaty ending the Federation-Cardassian War, Macet punished Telle when the latter was caught attempting to access secured systems aboard the Enterprise. Ultimately, the Phoenix was located and returned to Federation space. However, Picard relayed Maxwell's allegations of a renewed Cardassian buildup to Macet, warning him, "we'll be watching."

2370s
In the later stages of the Dominion War, Macet was part of Corat Damar's resistance against Cardassia's Dominion oppressors.

In May of 2376, Macet and the Trager aided in the evacuation of the Europa Nova Colony. This was Macet's first encounter with Kira Nerys.

In July, Macet returned to Deep Space 9 with Ambassador Natima Lang with an overture of peace to the Bajoran people, the paintings of half-Bajoran/half Cardassian woman Tora Ziyal.

In August, Macet took Vedek Yevir Linjarin to Cardassia to make contact with the Oralian Way and to recover four missing Bajoran orbs from an abandoned Obsisian Order laboratory.

Later that month on Deep Space Nine, a parasite attempted and failed to take control of Macet. With the Cardassians apparently resistant to the parasites, Macet, at the request of Starfleet, lead up a force of Cardassian ships to lockdown the Bajoran sector in the hope of containing them.

In December 2376, Macet was on Cardassia and was involved in a hostage negotiation.

Background Notes
Macet was the first Cardassian seen in the Star Trek'' saga. He was played by Star Trek veteran Marc Alaimo, who would later play a much more famous Cardassian, Gul Dukat.''
