From its inception, the "TSL" project's stated intention was to give closure to the King's Quest series with the belief and assertion that the project was legal under U.S. fair use copyright law, though acknowledging that this was a legal gray area. The developers maintained a notice on their site promising to end the project if confronted by Vivendi Universal, the owner of the King's Quest license. In September 2005, after over four years of development, and immediately after providing their first trailer and announcing a release date, Phoenix Online Studios received a cease and desist e-mail from Vivendi. Phoenix kept their word and immediately halted all development on the project as they entered negotiations with Vivendi. Once the news was made public, fans of the game and the series began a mass mailing and e-mailing campaign organized by the Save King's Quest IX team to persuade Vivendi to allow Phoenix Online Studios to complete the project.
