The Ashen Messenger made his move.
He spread his arms, and his right hand gradually twisted and deformed. A torrent of high-temperature ashes gushed forth from his armlets, falling from the wrist and blowing up, as a fervent gust arrived. The ashes, glowing with blazing light, formed an ancient battle standard.
At a certain stage in the development of civilization, battle standards were seen as objects to boost morale on the battlefield.

Then, someone gathered these dust particles to reform them into weapons once more.
The flag of ashes was raised, and thousands of suns swelled suddenly. Those residual bursts drifted into the ghostly high skies of subspace, transforming it into a raging, molten Sea of Fire. Accompanied by falling fiery stars, all the Subspace Mages who surged forward like the tide were obliterated!
