@the_imperator Wait, you know how you said the Time Lords can turn off FVC? Could you show me a feat that shows that because that would speculation? Plus, isn't a lot of the Time Lords super-weapons have not been shown to actually do what it was meant to do, for example, the Ultimate Sanction, the Moment, and the Armageddon Sapphire? Also, isn't Faction Paradox non-canon?
This is from the comic Wormwood. The guy is using an Eye of Harmony made by a Time Lord robot gone rogue to literally turn vacuum particles and dark matter into holes in space time, to stop all space flight (the effect also seems to only work off of planets, showing the level of control an Eye of Harmony has).
The Time Lords have the original, and used it to set up physics. Given their arrival to the neutral setting, they would pretty much automatically alter physics to fit how they like it, which changes everything all at once, rather than in a wave as a FVC does. This facet of the Eye of Harmony is described in the Doom Coalition audio dramas as basically being the Time Lords building a modeling of reality, then using the power of the Eye to project this model onto all of space/time at once. This ability to touch all of space/time at once is a key point of the series five episodes The Big Bang/The Pandorica Opens, wherein the TARDIS explodes at every point in space and time (except Earth b/c the TARDIS doesn't want to die and is trying to save itself) at once erasing it all thanks to its Eye of Harmony.
