Calamity Beasts
Ves did not want to expand his collection of design spirits too much.
He preferred to surround himself with a network of intimate and committed spiritual friends rather than an army of strangers that could go rogue at any time.
If he desperately needed a specific kind of power or domain that his existing design spirits did not cover, then he could conduct a focused search for a specific kind of mutated beast that met all of his criteria.
Mutated beasts used to be rare in the past, but now they were popping up like mushrooms all across the Red Ocean.
Many of them originally used to be ordinary exobeasts. They minded their own business and tried to survive in their own exotic environments, when suddenly E energy radiation caused them to grow stronger, smarter and weirder at a rapid rate!
No one had a coherent explanation why this was the case, and why it only happened to creatures that were originally non-sapient.
