ON GALLIFREY, A TIME LORD SECRETLY COLLUDES with a masked figure to steal the Doctor’s bio-data extract, which they deploy in a failed attempt at ‘temporal bonding’.
The High Council of Time Lords is alerted to the presence of an antimatter creature, whose location is shielded from them. According to the Doctor, the only force capable of shielding antimatter is quad magnetism, created by the collapse of a Q star in an area known as the Arc of Infinity – a naturally occurring ‘gateway to the dimensions’. The Time Lords fear the antimatter could cause disaster, and conclude that their only course of action is to execute the Doctor before the creature can complete its mission to bond with him.
