Glinn Tajor is a Cardassian officer who accompanies Gul Lemec to the tense border negotiations aboard the Enterprise-D under Captain Edward Jellico in Chain of Command.
Tajor appears in Chain of Command, the sixth-season two-part story. He is one of the two aides, with Glinn Corak, who come aboard the Enterprise with Gul Lemec of the warship Reklar to discuss Cardassian troop movements near Minos Korva.
The talks are a contest of nerves. Edward Jellico keeps the Cardassians waiting, storms out of the first meeting and objects to the size of Lemec's party, and the aides are sent away so that the two commanders can face each other.
Tajor has little to say for himself, but he is part of the delegation that sits across the table while Lemec reveals that Jean-Luc Picard has been captured on Celtris III.
