I call upon the sword, the mighty Excalibur
Grant me the skill to fulfill my quest.
I call upon my king and the knights of the table round
Grant me the courage to stand to this test.
I call upon the seer, Merlin The Sorcerer
Grant me the magic to end my pain.
I call upon the spirit that lives in the noble heart
Grant me the passion and held my vein.
Shades of the dead are sliding on the wall,
Demons dance in the castle hall!
