Photogen

"The witch's care was that the child should not know darkness. Persistently she trained him until at last he never slept during the day and never woke during the night. She never let him see anything black, and even kept all dull colors out of his way. Never, if she could help it, would she let a shadow fall upon him, watching against shadows as if they had been live things that would hurt him. All day he basked in the full splendor of the sun. She brought all her knowledge to bear on making his muscles strong and elastic and swiftly responsive -- that his soul, she said laughingly, might sit in every fibre, be all in every part, and awake the moment of call. He was the merriest of creatures, always laughing, always loving, for a moment raging, then laughing afresh. She called him Photogen."
