Origo
It was said that in order to acquire a piece of diamond, a great amount of pressure had to be applied to a piece of carbon. The carbon that could withstand the pressure and evolve was seen as good, while those that crumbled were seen as trash.
Dante felt like a piece of carbon right now. The energy that poured into this tiny void that contained all of his existence began to apply pressure, squeezing every aspect of him together like he had entered a small car with two very big-boned people on either side of him.
The more 'he' was pushed together, the more the various parts of 'him' began to forcibly use and merge. This process was not free of pain, but 'he' did not have the facilities nor organs to sense pain physically, but 'he' felt it on a spiritual level.
