A Federation outpost where Cardassian forces killed many civilians during the war, an attack that shaped Benjamin Maxwell and Miles O'Brien.
Setlik III was a Federation outpost during the Federation-Cardassian War. Cardassian forces attacked it, believing it was a staging base for an invasion, and many civilians were killed. Captain Benjamin Maxwell lost his wife and children in the massacre, and Miles O'Brien, then serving under Maxwell, was among those who fought there.
In The Wounded, the memory of Setlik III drives Maxwell to attack Cardassian targets even after peace has been agreed. O'Brien's recollection of the fighting there also explains his lingering hostility toward Cardassians.
