[The Eternal Prison, Pigmen World, Sulthar's POV]
Every 10 years a Dragon's one scale changes color — Sulthar had learned that by observation of his own body. Every 10 years, one among thousands of his scales would turn half blood-red. He had only seen the last few of his full black ones turn blood-red in the end.
Sulthar had thousands of such scales, already half blood-red, when his father gave him the gift of life. Thousands of years wasted, in that confined, suffocating, restricting space. Mindless violence and savage fury — that's all Sulthar remembered of his thousands of years old life.
"A piece of me resides in you, Sulthar." He remembered the words. "That makes you my child."
