He asks: “Is it this winding down and clearing of trauma records in the akashic records that is needed to activate the Ascension? Is it thus fair to say that interloper time travel is a critical obstacle to the Ascension?” What is Creator’s perspective?

The consequences of time travel are not the greatest obstacle, it is the sum total of everything which is the rate-limiting factor, both individually and collectively. Ascension is intended to serve the collective of humanity, at least the great majority, knowing there will likely be holdouts who do not cooperate with preparations needed for themselves, individually, to participate. Ascension will not begin until there is enough healing for a majority of human beings, for it to be successful. That is another reason you are all in this together, because your fate is interdependent with the many other humans on the Earth.
