Apollo blessed the people of Parnassus and they built a sanctuary for him at the headwaters of the Castalian Spring and they named it Delphi. They lived their in quiet for many years, haunted only by the mists of Python.
In time Apollo wished to grace the sanctuary with music; and he took to the sea in search of the ancient Cretans for they were known far and wide for the beauty of their voices. Finding a ship off the coast of Knossos he cast himself onto the planks in the form of a dolphin and called upon the people there to follow him. They did, in fear at first, but later with joy. These in instilled in the Sanctuary so that their voices carried over the land far and wide.
Ever did they breathe the mists of Python and these changed them. Their voices, so angelic became fused with prophecy and in time they could foretell the future. And a great priesthood grew up around them and Greeks came to the Pythia in time to seek aid and comfort or reason and being.
Thus it stood at Delphi for a thousand years, where man dwelt in the shadows of gods and their deeds. But the later Romans took affront of the Oracle and destroyed the temple and burned the sanctuary and scattered the mists of prophecy. So that now Apollo alone comes to Parnassus, drifting through the shadows of the dying sun, to breathe the mists of Python, cast about his memories and muse upon the power of his people now gone.
