Figures out Endbringer durb

But it was getting harder. Not that I was slowing down, but that each cut was less effective, each slice carved away less flesh than the one previous.

Fifty. Fifty-five. Sixty. Seventy. Eighty.

The damage I was doing was decreasing. No, rather, the durability of the flesh I was cutting was increasing. The thinner surface layers had been carved away and destroyed, the middle, hardier layers obliterated, and I was reaching now the incredibly dense, incredibly durable inner flesh, that which formed the base skeletal structure and, at the deepest parts, the core.

Impossibly dense. Impossibly durable.

It was matter that surpassed the tolerances of the given material, going beyond mere density and strength. It was a material without flaw, without imperfections in the crystalline superstructure that would allow for points of fracture under the stress of my blade or my fists. It was an impossible material that surpassed earthly limits, despite giving no indication of anything like an Authority that would allow it such a property.

[It is not divine power derived from Authority or a blessing, nor an exotic material. Its mystical weight is too low.​]

Then, what made it so durable? If the matter was the same, but the density increased beyond what was possible for this world, how did it manage something like that?

Herakles’ incredible mind and intuition had already found the answer.

A dimensional folding phenomenon. Increasing the durability of the flesh in the same manner as certain kinds of sword techniques by folding multiple instances of a singular event or object over each other through extra-dimensional manipulation. It was not simply a matter of coming up against more matter as it was that the matter was folded over itself by refracting it through multiple higher dimensions.

[A frustrating defense mechanism.​]
