The "Black Wolf" pack is the splinter pack that was formed when Jacob Black broke away from the {{#replace:La_Push_Wolfpack|_| }} and Seth Clearwater insisted on following him, soon also joined by Embry Call and Quil Ateara. For a while it was known simply as "Jacob's pack," but eventually Jacob give it a more official name, combining his surname, Black, with a translation of the surname of his mate, Jason Christopher Lupus Lupus: thus, Black Wolf. At Jacob's desire, Jason has since come to be accepted as co-alpha of the pack, while Embry serves as their their "second" in the pack.
The pack claims territory primarily between {{#replace:La_Push|_| }} and {{#replace:Forks|_| }} in the {{#replace:Olympic_Forest|_| }} , around the {{#replace:Ancient_Chapel|_| }} , but they also close allies with the {{#replace:Quileute_Wolfpack|_| }} and the {{#replace:Olympic_Coven|_| }} and assist in protecting their lands, as well. They are also allied with the Beacon Hills Pack and on good terms with {{#replace:Angel_Investigations|_| }} . Jason Christopher Lupus's personal holdings are generally open to members of the pack, as well.
