If combat between Legendaries occurred in a living world, the damage could only be described as catastrophic. In such strife between super lifeforms, flattened cities and severed mountains were fundamental, while if things went a little more serious there would be earthquakes that stretch over a thousand miles, causing the environment to shift permanently. The worst-case scenario was in turn global weather change, causing long droughts in certain regions throughout the year or tidal floods.
Whatever the case may be, Legendary individuals could make a nation fall as a stable and prosperous land into a barren, lifeless place—one could never be too cautious in regards to such destructive forces.
That was why, having seen the two Legendary mages combining to tremble the void and tear away an area of several hundred miles with the most profound of magical power, both the gigantic Burning Eye and the Deity's Crest stopped in their tracks.
