The Crystal of Achillon is the first fan Doctor Who story from The Projection Room. It was released onto VHS in August 1994, and onto DVD in 2007. The previous story, The Glass Cage, is an un-recorded adventure linking the end of Sylvester McCoy's era to the beginning of Chris Hoyle's tenure, although a 5-chapter 'novelisation' of this story is available on The Projection Room's 'Facebook' group-page. The subsequent adventure, A Spoonful of Sugar, is also missing and currently un-written. The next existing adventure is The Invisible Opiate.
