Nigon is the second underground race.

I haven't played Might and Magic. And I'm creating a race for the 5th game, and the world is completely different in the 5th game! Have you forgotten?

You named the race Nighon and claim that there were no Hydras or Rukh in Nighon. How is this related to the somewhat mediocre world of the 5th Heroes game?
