The hallowed air of the Eternal Paradise temple thrummed with whispered devotion, thick with incense and deceit. Douma rested in his inner sanctum, a masterpiece of tranquil fraudulence, his multicolored eyes watching the door. His hair spilled like pale silk. Then, the expected narrative shattered.

The very atmosphere transformed, the pretense of pious compassion evaporating into something taut, private, and lethally intimate. Here sat the Upper Moon demon, a being who withered in sunlight and feasted on deception, yet his still, cold core held a singular, secret pulse—reserved solely for the one human he kept hidden from his master's annihilating gaze.
