Timonic Fusion Device

 was a temporal weapon often theorized, but thought to be impossible to create. A secret project on Gallifrey called Project Alpha succeeded in building a prototype, but it was deemed unstable and dangerous and thus was dismantled. Very few Time Lords knew of the weapon's previous existence. A Timeonice Fusion device was used by the subversive organization Free Time, although the weapon was never detonated due to Free Time being unwittingly used as a pawn in a greater scheme put in place to discredit President Romana.
