"The smell," Dawn said. It was not that hard to figure out the reason why the northern warriors had been having a hard time to sleep.
It was because of the smell that came from the area where they burned all of the traitor dead bodies after they hanged them.
They killed them at day and burned them at night, that was why they were having a hard time to sleep.
