"As in a dream, you see yourself tumbling down a great, dark staircase.
All about you are shadowy images of struggles against fierce opponents
and diabolical traps. These give way to another round of images: of
imposing stone figures, a cool, clear lake, and, now, of an old, yet
oddly youthful man. He turns toward you slowly, his long, silver hair
dancing about him in a fresh breeze. \"You have reached the final test,
my friend! You are proved clever and powerful, but this is not yet
enough! Seek me when you feel yourself worthy!\" The dream dissolves
around you as his last words echo through the void...." CR>
