N is not located in Anville Town.
whe your n nimbasa city, go tothe train station and look for the train that takes you to anville town
you get it from a girl in undella town but you must beat n before you get to that town. sorry
You meet N in Accumula Town after Professor Juniper gives you a tour of the Pokemon Center.
There are actually 2 regions on pokemon Black/white, many people say there is only one, called Unova, but truthfully there are 2. To get to the second region, (called Meiri), you have to defeat the remaining 6 sages of Team Plasma after defeating N and Ghetsis, and 'completing the game'. What people don't know is that if you travel to a city on the outside of your map, called Anville Town, you meet N's brother, M, who is ashamed of what his brother has done and glad you defeated him. He will give you a Shimmering Scale, which powers up dragon-type moves and leads you to the released Kezrom/Reshiram (whichever N captured, then released). Zekrom/Reshiram will be found in a tower called Jolt Tower or Flare Tower, depending on if it's Zekrom or Reshiram. When you capture Reshiram/Zekrom, N and M will meet up, tell you that they're glad you captured the legendaries, and then show you to a hidden path behind Anville town, which leads you to Meiri.
You get the national pokedex from Cedric back in Nuvema Town after you defeat N in the champion battle.
After you defeat N and Ghetsis, go to Undella Town and a girl will give you the HM Dive.
You will encounter N many times in Pokemon Black & White.
In pokemon black you can get it at N's caslte
N is a PERSON
You will see a girl in Undella town She gives you dive. But you need to beat N first to go there
