McAnally

McAnally, usually called Mac, is the owner of McAnally's Pub. He is first introduced in Storm Front.

Description
He is a tall, gangly, man with a shaved head. His actual age is indeterminate; "somewhere between thirty and sixty." When he works, he wears black pants, a white shirt, and a white apron that's always spotless. He is a man of few words and few overt expressions, but when he says something, or emotes, it's worth paying attention to. He seems to be generally very wise and unrufflable.

Biography
He is something of an unsolved mystery throughout the series. To all appearances, he's not anything but human, yet he knows an enormous amount about the supernatural community, and has managed to make his bar neutral territory under the Unseelie Accords. He seems to be on first-name basis with both of the Faerie Ladies and Fix, as well as with Anastasia Luccio and Donald Morgan.

He makes the best ale in Chicago, and gets irritated if you want it served cold, as that takes away all of the flavor. He also makes lemon ice-cubes to go with his lemonade, so that it doesn't get watered down. He specializes in steak and steak sandwiches. He speaks at least a little Japanese. He drives a white '89 Trans Am.

He is the first person Harry Dresden talks to about his daughter.

In Small Favor, Murphy faces down an enormous Gruff who enters the Tavern, Harry calls him Tiny, and gets him to leave of his own accord, more or less. This so impresses Mac that does something he rarely does. He brought three bottles of a special brew he usually holds back in reserve to the table where Harry and Murphy were sitting. He opens and hands one each to Harry and Murphy and opens one for himself—then he salutes Murphy with his bottle—then he chugs down his whole bottle.

According to Jim
According to Jim Butcher, more wll be revealed about Mac later on the series. He's not a god, nor the scion of a god. He is dangerous, however.
