The greatest game
Our tale starts in Salazar's home. His girlfriend Nagini is visiting after finally being freed from Voldemort's service.
Nagini said, "That was a great game, Sal."
Salazar smiled. "The greatest game of chess ever, I believe. The stakes were high, but I, Salazar Slytherin, the greatest Slytherin of all time, beat the odds and won my charming girlfriend's freedom from the clutches of evil."
Nagini smirked. "It was only a chess game."
Salazar beamed, "It was the best chess game I have ever played, Gini, because I saved you."
Nagini grinned. "Don't go sappy on me now, Sal."
Salazar chuckled. "Me, sappy? I am Salazar Merlin damn Slytherin, not Helga Hufflepuff."
Nagini laughed. "Oh, I know. I chose you not Helga. You're insanely ambitious and a tad evil just like me."
Salazar sighed. "Have you learned nothing from our time together, Gini. I am more than just 'a tad evil', I am very evil."
Nagini smiled. "Oh, I know."
