Reconstruction

"The Grandmaster taketh away, but he can also giveth."

--Unknown

Although the nature and extent of this particular power is unknown (and perhaps unknowable), it appears that the Grandmaster can use his powers of Deconstruction to also create--an ability that is termed "reconstruction." Because evidence points to the fact that Marsh has deconstructed the universe, but the universe still exists in the present, the only conclusion that can be drawn is that Marsh was able to reconstruct the universe after its deconstruction.

It seems likely that early humans encountered this power and documented it in a book entitled Genesis, in which the Grandmaster was mistaken for a god.
