Noah had found his true meaning in his oldest memory. His experiences paled in front of the purity that his ambition had been able to express when it first formed.
His ambition was an energy that defied levels of power, limits, and laws. Its only purpose was to bring Noah more power, and it didn't matter which method it used to do it.

The invisible walls of that dark place expanded. The separate dimension enlarged due to the pressure radiated by Noah's aura, but his ambition modified their very structure.
Matter began to appear on those walls. Large patches of a gaseous material condensed inside the limits of the separate dimension and improved their sturdiness.
