Someone From Heavenly Palace?

The dust flew, and a man galloped towards the August Capital on his horse. His face had been obscured in the hood while he wore a long black robe that fluttered in the wind, as he dashed towards his destination. There was an insignia embedded on his chest, under that insignia wrote a word: Heaven. 

After riding the horse for a certain amount of time, the rider looked in front of him and saw a colossal city gate in front of him. He did not decrease his speed, instead, the horse paddled its hooves faster than ever on the hard creaked ground. 

"Halt!" a shout came from up ahead, but the man disregarded the voice and continued to sprint on his horse towards the gate. "Stop, or you will be hurt!" another shout and again no reaction from the black-robed man.
