to be added
Constance mentions the TARDIS always getting lost.
The Doctor mentions Cartesian geometry, which involves 26 dimensions.
Parallel universes aren't supposed to meet, hence the word 'parallel,' but there are various points in the universe where the parallels collide.
There are other dimensions that, while they can't be called " evil" since that's too subjective, are nonetheless darker, but these darker dimensions are usually "safely" away from the nice ones.
The Normans are "Normal Animates," since "normality" can have various meaning in different realities. They were grown by the Parallel Sect.
The longer the dimensional barriers are broken, the more dimensions collapse into infinity with accelerated "normative entropy."
The Master uses his TCE.
The Master's TARDIS is disguised as a ticket machine.
Keith Potter is an avatar, operated by the Master from the safety of his TARDIS.
The Valeyard claims the dimensional nexus point as his domain, where he's been re-invigorating.
