Discordia is an online interactive experience based on the Dark Tower series. Independently produced by StephenKing.com, Discordia chronicles The Tet Corporation’s interdimensional efforts to save the multiverse from destruction at the hands of Arina Yokova.

Although not written by Stephen, in many ways, Discordia is an adjunct to the Dark Tower series as a whole. With detailed 3D artwork and an elaborate storyline authorized by Stephen, Discordia is a work of interactive fiction by Brian Stark, Judy Hahn, Robin Furth and Marsha DeFilippo.
