"Have you ever seen an eternally shining sun suddenly split open a monstrous abyssal maw and devour everything?"
"Have you witnessed a dark-green sun under whose radiance all life rots in situ, transforming into a deadly sludge?"
"Have you observed a black-gold sun, where all life illuminated by it ages, even demons that have lived through long eons—bodies withering, bones calcifying, eventually lying on the ground waiting for death?"
"And then, the surge of numerous monstrous creatures, hunting everything, entranced into a frenzied battle lust by the illuminated scarlet sun."
"All of these suns exist in the Abyss, each one a "Great Terror" that occupies a layer of the Abyssal Plane."
"They are named respectively: the [Great Day of Starvation], the [Green Day of Decay], the [Ancient Sun of Aging], and the [Day of the Hunt]."
