What do you call it?” Twilight asked suddenly, breaking the princess out of her morose mood.  
“Call it?”  
“If it’s a mixture of day and night you can’t call it either.” Twilight explained while looking up at her. Celestia knew her star student was right and silently praised her as she watched the pre-dawn display. She had an idea then while looking at the bright pinks and purples mixing with the darker blues as night began to wane. “I have the perfect name” She said finally, but by this time the little filly had fallen asleep. She kissed Twilight’s head and watched as night and day shared the sky “I shall call it Twilight.”
