The Silver Lining (TSL) is an episodic video fangame based on the King's Quest series, which was developed and released in free download format by Phoenix Online Studios for Microsoft Windows starting in July 18, 2010. While five chapters were planned, the most recent release, Episode 4: 'Tis in My Memory Locked. And You Yourself Shall Hold The Key Of It, was released on November 8, 2011.

Although the game features 3D graphics, its gameplay departs from Sierra Online's last King's Quest release, The Mask of Eternity, which was mainly criticized for its RPG-like atmosphere, and settles into that created by the previous titles (for example, the setting returns to the land of the Green Isles, visited in King's Quest VI: Heir Today, Gone Tomorrow, while some recurring characters include Mannanan from King's Quest III: To Heir Is Human and Pan from King's Quest IV: The Perils of Rosella). The plot itself revolves around King Graham as he desperately seeks the help of ancient druidic artifacts to undo the evil cast upon his children, Alexander and Rosella.

The fifth and final episode for the series, A Thousand Times Good Night, remains in development in 2020 after multiple delays since 2011. Since Phoenix Online Studios changed its name to Phoenix Online Publishing on 19 May 2014 in order to respecialize for publishing of independent quest games and focus on more profitable endeavors. The company soon made a statement of releasing all rights to the game to Activision upon request. In August the same year, Activision began to collaborate with its Sierra Entertainment division on new King's Quest game.
