A long time ago, the sorcerer Yen Sid created a pen-and-paper world for forgotten Disney characters, held in an intricate model on a table, and accessible through a mirror. Mickey, who finds himself inside Yen Sid's study, sees the model, and waits until Yen Sid is gone before going back to take another look at it. Mickey decides to create himself using Paint but instead creates the Blot. Mickey tries to clean up the mess he made but instead spills Thinner on the model, allowing the Blot to enter the Wasteland. Mickey manages to escape without Yen Sid knowing, returning to his world where he went on to live to years of success and fame, but his meddling had consequences. The Thinner Disaster allowed the main antagonist of Epic Mickey, the Blot, to invade the paper-pen world, resulting in a series of wars with the world's ruler, Oswald the Lucky Rabbit in the Blot Wars. The Blot wins over this struggle, and Oswald now blames Mickey for all this fiasco. Mickey, already plunged into the world by the Shadow Blot, must gain the trust of Oswald and defeat the Blot once and for all.
When Oswald was cast into Wasteland, the love of his life, Ortensia, naturally followed. She, Oswald, and their 420 children lived happily, ruling the world of forgotten characters and welcoming all toons were met with a similar fate. Little did they know that a little bit of spilled thinner would change everything. (more..)
