The Starfleet commodore in charge of the Earth outpost on Cestus III, famed for his hospitality, who died with his garrison when the Gorn destroyed the base in 2267.
Commodore Travers is spoken of in the episode Arena but never seen alive. As the Enterprise approaches Cestus III, Kirk and McCoy look forward to dining with him; his table and his personal chef are well known in the fleet.
The invitation asking Kirk to beam down with his tactical officers turns out to be a fake. The outpost had been wiped out a day earlier, and the messages were sent by the attackers to draw the starship's senior staff into an ambush.
The one survivor, Lieutenant Harold, describes how the base was hit without warning and received no answer when it tried to surrender. Travers's fate drives Kirk's determination to chase and destroy the Gorn ship, until the Metrons intervene.
