Realm of Fire
Both Adhara and Ugrok are Fire Elementalists.
A sudden change in mana level in the surroundings was detected by them instantly, and the fact that the change revolves around the mana content in the surroundings turning into fire mana makes it even more obvious to them.
It was a phenomenon that Adhara experienced for the first time.
Normally, an area contains a blend of mana in the air, and the environment will determine the prevalent mana type. For example, near a volcanic terrain, the concentration of fire mana would undeniably surpass the other elemental mana.
However, the presence of the Elemental was able to disrupt the mana concentration.
Almost as if it was the environment itself.
Just the presence of the ancient Elemental alone was able to turn other elemental mana into fire mana which shouldn't be possible. It was supposed to only be viable to the will of nature, but it seems the ancient Elemental itself acts as the extension of nature.
