Delphi was a city in Greece, famous for its oracle.
Delphi was visited by Bernice Summerfield and Jason Kane in 430 BCE after they used their time rings to travel back in time. (AUDIO: The Oracle of Delphi [+]Scott Handcock, Bernice Summerfield: Single Releases (Big Finish Productions, 2006).)
In 279 BC, Brennos's army of Celtic tribes sacked Delphi and burned the Temple of the Pythia after defeating Callippus of Athens at Thermopylae. That night, he was found in a pool of his own blood, leading to a chain of events that secured the stability of the Eighth Earth Front.
