Earthfire Valley.
A silver sword blank hovered above the center of the sea of flames.
Ultimate Fire swept across its blade.
Impurities in the sword blank turned to black smoke and dissipated.
The Ice Dragon King raised a claw.
An icy blue glow fell upon the sword blank.
The metal, red-hot only moments ago, cooled rapidly.
Fine lines appeared across its surface.
Before those lines could fully set, the Fire Dragon King's origin flame descended again.

The Vast Sea Cosmic Shroud had lost its original form.

The Ice Dragon King looked toward the edge.

The Fire Dragon King spread his wings.
A crimson dragon apparition rose behind him.
The earthfire throughout the valley poured into it.
The Ice Dragon King followed close behind.
An azure dragon apparition coiled above the sea of flames.
