Blackfeather Woods A stick can save a life.

Burke walked on, marking a tree or even the ground sometimes with a bit of pee. He wanted to be through when marking these borders. The swamps had already a peculiar scent so their scent had to be stronger than that. He appreciated Macbeth pointing out where he couldn't walk, even though he could smell perfectly where he could walk and where not. 

Burke changed his course when Macbeth pointed out another swamp. He stopped to mark again and placed a tree down. "You can mark too you know, just so there will be more scent around this border," he explained. If Mac wanted his Mercenary trade then he would have to do some guardian aspects too, perhaps, unless he wanted to full focus on being a warrior.
