Dorian had asked to join Draven on his patrols, with no ulterior motive to join his pack. He had struck up a conversation with the wolf and decided that this was as grand an adventure as any, even if he had already been in this portion of the forest today. In demonstrating his speed (not only in speaking but in running), Draven opened this possibility of joining "Non Sibi" to Dorian. Initially worried at the prospect of settling down, Draven made it clear that Dorian could become his scout and venture to the depths of lands untrod.
