Slicing your spine into coasters would cheer me. May I?— Cat SithHe presents himself to Harry Dresden simply as Sith and Dresden quickly realizes that he is in fact "The" Cat Sith The King/Progenitor of all the malks. Mab has assigned him to assist Dresden, something he does grudgingly, but with good humor. It seems that in time he warms up to Dresden.
He is a huge malk, maybe eighty or ninety pounds, the size of a young adult mountain lion. His fur is pitch-black, apart from a white spot on his chest. He has an enormous aura, that can be felt from across a large room. His eyes are gold, and his shadow appears to be about the size of a billboard, more in proportion to his power level than his apparent size.
In the seriesEdit
In Cold Days, Sith shows Harry Dresden the portal that Mab created in Dresden's linen closet leading directly from Arctis Tor into Chicago. He informs Dresden that it's the only way into or out of Faerie until dawn giving Dresden a head start on his enemies for his assigned mission: kill Maeve. He also provided him with a car, an old WWII-era black Cadillac.
Dresden summons him to Thomas Raith's apartment and tasks him with "distracting" anyone who has Harry Dresden and Thomas Raith under surveillance without killing or maiming. Sith huffs at that so Dresden strokes his ego by saying "any idiot can murder them. What I ask is far more difficult as befits your station." Sith's tails swishes to the other side thereby seeming mollified. When exiting the building, Dresden found the doorman on the ground with several long slices in his leg and a patrol officer with the first aid kit.
Cat Sith pops into Thomas's Hummer informing Dresden that the meeting with Lily is set at the Botanical Gardens and he must go alone. He fights Redcap and his Sidhe helping Dresden and his team escape. Later, when Dresden tries to summon him—he didn't appear.
At the end, Sith is taken over by the Nemesis. He had been jumped by He Who Walks Before covering Dresden's exit at the Botanical Gardens. Although the Malk tries to fight it, he succumbs to it. Dresden throws him over the side of a boat into Lake Michigan.
