Watched it, it was cool I'm gonna continue. But is the first guy a jarl or something and then his brother is like king of the north?

Ned (Sean Bean), is the Lord of the North. There are seven regions all reporting to one king, the north is one of them.

The King, Robert, was raised alongside Ned, they were once very close, but not actual blood brothers.
