Nis was from a very very young age as perfect as someone can be.
While growing up Nis legend was growing. Perfect grades at school, perfect behavior towards everybody, always present and ready to help. He was what every parent always desired as a son.
In his high school bloodbowl team Nis could have been the star but he was a team player, sometimes taking hard hits if that was what it take for the play to be successful.
That behavior in a thrower was abnormal but it was exactly what coach Estika was looking for, someone who could help defense and at the same time start the attack quickly, the best of two worlds.
When Coach Estika left the game, he knew he had found what the was looking for, he just found perfection.
