Far too many pointy objects
He’s a tall, fierce looking man approaching middle age, well suited to his life in the wild. The observant will notice that there are irregular brownish patches here and there on his clothing.
Roland was always peculiar. He was the sort of child that did terrible things to animals, and that no mother would allow her children to play with. He was barely out of boyhood when he first killed a man. He was not caught. Not that time. He had discovered that he liked killing, and tried again. It took two more murders for the town authorites to connect him with them, and Roland was forced to flee in the night. For a time, he joined the army under an assumed name, and that temporarily satisfied his bloodlust. But after members of his unit started turning up dead in peacetime, Roland was again on the run. He ended up in the Western Woods, where no one would follow. He did not fear the strange creatures of the forest, for they can die just like everything else. As long as he didn’t come to the attention of the powerful fey lords, he could do as he pleased.
Of course, when your hobbies are of the sort that Roland’s are, it isn’t long before you come to the attention of the people in charge. It was Lady Joya who took notice of Roland first, which is the only reason he isn’t dead.
Joya decided that it could be useful to have someone like Roland in her territory, and she made a deal with him of sorts. She allowed him to stay in her territory, and he patrols it by day. He is allowed to kill any tresspassers, a task he relishes. Periodically, he will stray from Joya’s borders into other realms to satisfy his bloodlust, but he is on his own then. He has also joined the Great Hunt a time or two, but he doesn’t much care for it.
Roland is just your average homicidal psychopath. He enjoys stalking creatures and killing them, which is why Joya finds him useful.
Joya is pretty much universally feared throughout the forest, but Roland is feared almost if not as much as she.
Joya is not a fool. She is well aware that Roland is dangerous. That is why she used her considerable power to entrance to ensure that Roland would be loyal to her. Despite that, reason demands that he doesn’t know where her lair is.
Joya puts up with Roland, but the other lords of the forest will have no mercy on him if they catch him in their territory.
