After Captain Benjamin Sisko's discovery of the lost city of B'hala in 2373, Koral was one of those who helped to excavate it. In 2374, after the tunnels below the city were excavated, a tablet bearing the inscription "Welcome Emissary" was found. He then contacted Sisko aboard Deep Space 9 who visited him in the caves to view the tablet. (DS9: "The Reckoning")
