Nucleus

A Nucleus is an organ possessed by every Kreature.

Properties

The function of a Kreature's nucleus is to emit its Nucleo-Aura, a protective forcefield that is the source of its powers. Its secondary function is to produce the extradimensional particles which compose said aura. If a Kreature is severely injured, its nucleus can convert small amounts of surplus aura into large amounts of bodily tissues in order to regenerate. Thanks to this healing factor, Kreatures can survive heinous injuries that would be fatal to humans or animals, even the to the heart or the brain. Most Kreatures regenerate gradually, with the length of time required varying depending on the amount of damage; it may take just a few minutes or several hours. Some Kreatures, such as Geksaur, can regenerate body parts in mere seconds, albeit at the cost of a lot of their stamina. However if the nucleus itself is destroyed the Kreature will die.

This ability can be exploited by Kreature Bioengineers. In a process similar to taking a cutting from a plant, nucleus samples from donor Kreatures are extracted and spliced in the lab, then put in regeneration chambers with nanites and an aura-rich nutrient slurry to hasten their growth. This allows Kreatures to be easily mass produced.

The nucleus is typically stored in a secure section in a Kreature's anatomy, such as in its center of mass, but the exact placement varies from one species to another. Some Kreatures with amorphous bodies, such as Slimok, Goosprite and Gasplorg, can even shift their nuclei around. Battle Kreatures are engineered with nuclei that are extremely compact, enabling them to emit powerful auras while also being small enough in stature to be practical to keep in captivity.

Domonids, Silarcs and Dolneans are technically Kreatures and as such, possess nuclei which emit auras. Micro-Kreatures also possess nuclei, but theirs are too small to emit a full aura.
