While it will be an adventure game like the previous games in the series, the interface will not be point-and-click. The game is one of several attempts at developing a ninth game in the series.
King Graham shares his previous adventures with his curious granddaughter, Gwendolyn. It is through these tales that Gwendolyn learns about the life led by her grandfather. In his story Graham enters into an old well, to fight a dragon, and find the magic mirror hidden there.
