The Order of the Rectangle was a mystical secret society created by Faction Paradox (PROSE: Interference - Book One) and noted for their usage of the rectangle, mostly as a symbol on their daggers. Robert Hay was a member of this brotherhood; when he learned that the First Doctor could travel through time, he labelled him as "Behemoth of the Supreme Order of the Rectangle". The Order played both sides of the infamous Gunpowder Plot in 1605. (PROSE: The Plotters)
