Vortex rupture
From Tardis Wiki, the free Doctor Who reference
A vortex rupture was a rupture in the space-time continuum capable of damaging the Web of Time, (PROSE: The Quantum Archangel) a geyser of time spillage caused by a massive detonation, the equivalent of a black hole forming, within the Time Vortex. If unchecked, the space-time continuum would lose the structure of the vortex and the galaxy would drop out of reality. (PROSE: The Crystal Bucephalus)
Anjeliqua Whitefriar bonding with the Lux Aeterna nearly caused a vortex rupture before she broke free, transforming into the Quantum Archangel. (PROSE: The Quantum Archangel)
