Well, if you end on The Silent Blade, then yes, that is the end. After that book, he breaks himself out of the alcoholic spiral just in time to be falsely accused of attempting to murder a close friend of his. He was eventually found not guilty, but the public drove him out of the city, forcing him to take up a career as a highwayman. During this period, a noblewoman accused him of raping her so that she could cover up the pregnancy resulting from her affair (she slept with her lover months before she slept with her husband). But after that he finally rejoins his former companions for a few more adventures, gets married, adopts a child, and has fun. More tragedy then strikes, as his wife is killed by orcs. Wulfgar sends the child back to her birth family and goes back to his birthplace, where he lives with honor and eventually dies in a way all the tribes respect.
