From the recording Hericium

In Erinaceus, we listen as the Kingdom of Hericium speaks among itself and the Mnenos Forest. Upon a closer listen, we hear a debate over the rights to dying trees, which Hericium is certainly interested in, as their Kingdom was ever-growing in size and scale.

As beautiful and elegant as the Kingdom is, Hericium shows itself as the dominant biological species upon The Body Incarnate. Perhaps this is why Qyo never considered their close Fulgen neighbor to their North during the Roses of War; that, and their neural-connection with the network of spores connecting the Trees.
