Blaze

"Congratulations your highness." the doctor announced "It's a colt."

Princess Celestia smiled weakly, after spending six hours giving birth to her newborn colt. The doctor handed Celestia the colt.  His coat was pure white and incredibly fluffy, his eyes were turquoise coloured and his mane and tail was white with turquoise running through it. The doctor looked at the princess and said "He looks like his father." Celestia's smile disappeared and she looked at the doctor with a serious look on his face "Now, I appreciate everything you've done for me, I really do. But nopony must find out who the father is. Do you understand?" The doctor nodded and asked "What're you going to call him?" The princess went silent and thought for a minute "Well." she said "A while back. His father and I thought about 'Blaze' so I think that would be the best." The doctor shook his head in agreement and picked up the birth certificate. "Blaze it is then."
