CaptainZeta Traal was a member of the Imperial Diplomatic Corps and was assigned to act as an official attaché to the royal regent Zelor on the planet Velmor in 3 ABY.[2]
Following the death of Palpatine at the Battle of Endor, the Imperial Diplomatic Corps found it had acquired a new role—keeping worlds already in the Empire from leaving. This task strained the resources of the Corps, and junior diplomats that would have been closely-supervised in the past were given greater autonomy as a result.[3]
