Waypoints, or Vortex Waypoints, were points in time and space that became supercharged with vortex energy.

During a temporal crisis which grounded TARDISes and similar machines throughout the universe, the Doctors realised they could only travel from one Waypoint to the next, draining each of vortex energy to temporarily, messily re-power their TARDIS before depleting their reserves with the next hop. (GAME: Lost in Time)

These Waypoints included:

• The UNIT Lab, which became charged with vortex energy due to "almost passing through the event horizon of a black hole" (GAME: Lost in Time) when Omega transported it to his anti-matter universe. (TV: The Three Doctors)
