Sword of the Vale Castle.
The flowing energy of the Dragon Vein was visible across the land.
As time passed, the Dragon Vein's energy gradually grew chaotic, but fortunately, it remained manageable.
At the Icirrus City Public Library, Cynthia had found the Dragon Vein's seven critical nodes by consulting ancient texts, and learned the best way to stabilize it.
Infusing the ley lines with peaceful energy simultaneously would put them back on course, allowing their energy to flow through the seven critical nodes.
Those assigned to the seven critical nodes
had begun arriving one after another.
The seven critical nodes were quite far apart, so they needed remote communication to inject their energy at the same time.
At that moment, only Li Wei, who possessed the Power of Overcoming, could achieve that by linking himself to the Pokémon.
With Darkrai's unique ability to travel through shadows, the deepest node fell to Darkrai.
Steven and Mega Metagross relied on Metagross's incredible computational ability and precise energy control.
Zekrom took charge of Eindoak Town, the central energy node.
Despite Zekrom being an Electric-type,
Zekrom actually represented yin within the Tao Trio.
Compared to Reshiram's power,
Zekrom's power was gentler.
It was simply that lightning always struck people as violent, creating a misleading impression.
Cynthia and Garchomp handled another node, where Garchomp's Earth Power would play a crucial role.
Meanwhile, Reshiram, who followed Ash, coordinated with Zekrom from afar, using the flames of truth to neutralize the energy within the ley lines.
For the sixth critical node, Lucario rode Corviknight and brought Regigigas to the Land of the Earth.
Glowing with blue light, Regigigas landed in the barren Land of the Earth, surrounded by wasteland.
The seventh critical node lay at the westernmost edge of the Unova Region, and Brock brought Diancie there.
