Crystallized Law supposes a sort of "substance of existence" that naturally seeks stability, coalescing from its raw state into spacetime and baryonic matter and all else, including stranger things with which we have no avenue of interaction. That which is formed from the substance of existence holds an existential pressure beyond its structured existence, sheltering it from that which would erode its rules or nature, and it is entirely willing to contaminate other powers- the substance of existence can take myriad forms, including information and patterns, which maintain that tendency towards stability.
A universe born of Crystallized Law is not just one universe. The original substance could not become a single perfect crystal of self-consistent rules, but cohered around a massive number of nucleation points. There are a vast but countable number of worlds with physical law so different they are unable to easily interact with us, most unsuitable for complex life but many potentially viable as sources of energy, matter, space and time to occupy, and exotic variations thereof to someone with sufficiently advanced methods. With even more advanced methods, it is possible to artificially crystallize new forms of physical law.
Substances operating under distinct physical laws in paradigms where they can mutually interact tend towards stability, under Crystallized Law. You can have a variant of elemental iron that enables controlled energy-positive fission reactions in arbitrarily small masses of any element heavier than iron, and it will retain without spreading its distinct behaviours even if you cast it into an alloy with conventional iron. In sufficiently extreme conditions, matter and energy can be converted from one Crystallized Law paradigm to another, even partially: this variant iron can be used to produce more of itself from conventional iron in a supercollider, and its exotic fission weakly adjusts the behaviour of atoms within a piece of metal until the structure itself is destroyed (e.g., melted).
Crystallized Law does not enable the defiance of entropy. The substance of existence is a finite resource, that itself obeys entropic principles. A certain quantity of the substance of existence manifested as "electricity" might be converted into ten times as much "electricity" that outwardly behaves identically but naturally retains a much smaller quantity of the substance of existence per unit. Resources can be stretched, and harvested from vast elsewheres, but cannot be truly multiplied, and are ultimately finite.
