Sky of Gold.
Once the gates of the {Elemental Vault} were opened, the element tapped into must run its course to completion.
Cain had broken the hold the vault had on the elemental star of metal trapped within the vault. Contained within this miniature star was a frightening amount of power. More than the sun of all the mana within his mortal body.
A Spirit's worth of mana...
Cain stared up at the sky, his eyes a bit glazed. The black dome created by him was already covered in cracks, courtesy of Obegrin, the {Sky Devils}.
Any moment from now, it was going to be destroyed.
But before then, Cain decided he was going to wreck the maximum amount of damage possible.
And so, he called upon the element of metal.
Cain was intimately familiar with this element. Although the metal he created appeared to be gold, it wasn't. Its lustre was golden, but it didn't have the same properties as gold.
