नीलाधिथ्या - the son of suryadhithya

Everyone know vasusen popularly known as karna from mahabharat. Some say he was most virtous man some say he was most vile in whole mahabharat. Some say he was one of the greatest warrior in mahabharat some say he was only a coward. So a story by me, a slight devitation from the original mahabharat also known as jaya(although the orginal jaya is lost).
This story is inspired by the birth of karna, where it was mentioned that lord surya spilt himself into two parts one as pritha's son and another to give light to the solar system
