Black pack

Jacob Black's Pack is a werewolf pack. It is led by Jacob Black and the second in command is Leah Clearwater. This pack was formed when Jacob accepted his Alpha history and decided not to listen to Sam Uley's authority during the last book of the saga, Breaking Dawn. Seth and Leah Clearwater joined when they thought they would rather be led by Jacob. This pack was instrumental in helping the Olympic Coven protect Bella Swan when she was pregnant with Renesmee Cullen.

After Jacob decided to fulfill his Alpha duty, he broke away from Sam Uley's pack and went off on his own. A little later, Seth Clearwater started following him because of his respect for the Cullens, with whom Jacob began spending the majority of his time. Two days later his sister Leah joined them so she could stay away from Sam and watch out for Seth. During their time with the Cullens, Leah and Jacob formed a friendship and Leah eventually became the Beta of the pack. After the tension between the two packs resolved, Quil and Embry joined Jacob's pack as well, something they were unable to do previously.
