The boat would eventually depart, Dalahar not the only illegal cargo on board. He didn't care where he was going, hopefully away from the whispers. Away from Ella, Shana, Candace. He could take care of himself and wouldn't have them in the firing line for him. He didn't deserve that understanding or compassion, that is why he left. A deep seated belief, faith even. Faith in his ability to do whatever it takes, faith that he could never change for any reason. He had to leave, he felt coddled. He was an astartes with all the combat prowess that entailed. With no greater purpose he could ply his trade in less hospitable lands, fight his own battles for his own reasons. Learn what it means to be free.
Dalahar will return at a later date.
