This reminds me of a game I used to play as a child: Broken Sword. It was a series of point and click games. Broken Sword II: The Smoking Mirror is all about the main character George Stobart, who finds an obsidian stone and soon discovers he must find two other stones to lock up Tezcatlipoca.
I was just about to write about the game, too. What a brilliant game it was.
I just made the connection between the title of the second game (Smoking mirror) and the plot when reading the article. I remember that I found the name of the game a bit odd. No wonder, when I did not realize that this is actually the name of the Aztec god Tezcatlipoca.
In Germany this game was called "Baphomet's Fluch" (Baphomet's Curse). The PS1 demo of this were George is surviving an explosion in a Parisian Café is one of my nostalgic gaming memories.
