Makbar was a Chief Archon on Cardassia Prime.
In 2370, she presided over Miles O'Brien's trial for smuggling weapons
to the Maquis. In fact, Makbar was part of an elaborate scheme to attempt
to discredit the Federation's policies and to establish grounds to invade
the DMZ to eliminate the Maquis. They attempted to portray the Maquis as
"savage, Federation-born killers" who were operating with secret but
official sanction from Starfleet Command.
The plot failed when Commander Sisko discovered that it was a
Cardassian agent disguised as Raymond Boone who used O'Brien's recorded
voice to steal the weapons from Deep Space 9.
As soon as the Chief Archon, Makbar, saw Boone she ended the trial and
O'Brien was turned over to Sisko. 'Boone' had been only a facet of a large
operation that was designed to discredit the Federation and to make it
appear that they were sanctioning the Maquis.
