Self-proclaimed Bandit King of the Southern Whitewood, Anders MacElroy had set up a fairly successful enterprise preying on travelers on the Bridge Road south of Theradyn. He had even begun construction of a fortress of sorts, carved into a cliff face south of the city, expanding on a series of natural caverns. He gathered several dozen like-minded individuals to his cause, creating a force to be reckoned with.
MacElroy was killed when attempting to flee from the party after failing to bribe them to spare his life. Mo crushed his head like a piñata with his mace.
