If we only look at the form of manifestation, the appearance of the power furnace is secondary; the important thing should be the concept of Purgatory. Coincidentally, there is indeed a God who holds the power of "burning everything to ashes," and that is the Blank God of the Land of Nihility.
Absolute nihility and erasure, where the manifestation of destruction is "burning."
Burning away filth and useless things, in essence, is for "purification."
Therefore, the ability that the Purgatory God suddenly acquired at the exhibition was—
"Purification and redemption. This obviously doesn't match my appearance at all. Moreover, my favored clan controls the power of refinement and restoration. Although it originates from me, they are all repair workers, completely unconnected to the heavily religious concepts of purification and redemption."
"Unless... my birth was orchestrated to repair something, such as the timeline of the Fourth Era that I once mended."
