Ryo stood at the edge of the vast cavern, forgetting to breathe.
Before him lay an underground world that stretched beyond sight.
Countless glowing crystal clusters jutted from the ceiling and floor, bathing the entire space in a soft light.
The brightness reminded Ryo of twilight.
The waterway he had followed converged here into a subterranean river that rushed through the center of the cavern before disappearing into the distant darkness.
Along the riverbanks grew thickets of bizarrely shaped Extraordinary plants.
The air was thick with Ether.
Every breath sent a thrilling tremor through his flesh and blood.
'This is the source.'
'So, hidden beneath the Gray Sea Marsh is an even more concentrated Ether-rich zone!'
Ryo's body trembled slightly with excitement.
