" For this is the thing the priests do not know, with their One God and One Truth; that there is no such thing as a true tale. Truth has many faces and the truth is like the old road to Avalon; it depends on your own will, and your own thoughts, whither the road will take you, and whether, at the end, you arrive at the Holy Isle of Eternity or among the priests with their bells and their death and their Satan and hell and damnation...but perhaps I am unjust even to them. Even the Lady of the Lake, who hated a priest's robe as she would have hated a poisonous viper, and with good cause too, chid me once for speaking evil of the God.

'For all the Gods are one god,' she said to me then, as she had said many times before, and as I have said to my own novices many times, and as every priestess who comes after me will say again, 'and all the Goddesses are one Goddess, and their is only one Initiator. And to every man his own truth, and the God within.'

And so, perhaps, the truth winds somewhere between the road to Glastonbury, Isle of the Priests, and the road to Avalon, lost forever in the mists of the Summer Sea.

But this is my truth, I who am Morgaine tell you these things, Morgaine who was in later days called Morgan le Fay. "
