In the Silver 2 ring, specialization became even more pronounced. The circular trees had divided into two distinct species through competition:
One was more oriented toward pure fire, which had developed almost metallic bark that reflected heat from the fire spirits now also living within them, and another that had specialized in purer wood element, growing considerably taller and developing more complex root systems and canopies to defend against the water from the round birds alone.
The Boars had also evolved correspondingly. Those living in symbiosis with the fire trees had developed extreme thermal resistances and the ability to generate flames directly, while those inhabiting the tunnels had developed better camouflage and excavation abilities.
"The earth ones have established a completely different niche," Ren pointed toward where they could see steam rising from the ground. "The Boars have formed alliances with the walking mountains."
