Samuel Muin was a guard of the Hazel Realm. He had been in the service of the boundary wardens for nearly five years. Samuel had a wife and three children whom he was forced to leave behind when he, along with every other guard from that land, escorted the princess Ysabelle on her journey to Greenreach. It was Samuel who captured Vespertilio, and was about to kill him when Godfrey Gelenos pointed out that the bat was merely a child.

He was among the squirrels captured by the Hobbers, and was killed while executing a plan by Godfrey Gelenos to retrieve the silver acorn.
