The city was in sheer chaos. Walls were shattered in small holes here and there, the dog vermin swarmed through. The soldiers fighting couldn't stop friends and family being rutted before their eyes, before they left just as quickly. Their attacks were unstoppable. That is when a malicious aura made itself known to the King Knight in his chambers where he silently tried to form solutions that would never work. In his state of helplessness, she declared to him...
"Mister Knight~ Son of Muller~" she cooed, "You seem to be in despair."
He grabbed his blade, and looked to the demon dragon. "Vat is zis!? You seek to fight me!? Unexpectedly honorable of you, DEMON!" he roared, before charging at her without hesitation. She lifted an arm, and soft human skin turned to invulnerable draconic scales, bouncing his blade clean off before she placed her other hand upon his face, and casting a magic that sent him flying backwards, tumbling over his desk and sending governmental papers everywhere.
"Please, Muller. You could never hope to hold a candle to me even if you were at the pinnacle of human potential. I've come to offer you a chance to save your kingdom. I hold the power to defeat your enemies." she declared.
Muller stood up and roared. "Ze very same you used to THREATEN ME!?"
"Aye, the same. I hope you understand the situation, but I need to put my colors on the board. Otherwise, what will my friends from the village do without my chaos to guide them?" she giggled. "Like moths to a flame, and you will hold the torch."
"Never show them your arm, for I have placed a curse on your wife and daughters. At a moment of my choosing they will find their minds broken and wrought with insatiable desire for the knotted cocks of the gnolls outside your walls. Betray me, and they will suffer. But if you're a good boy... You will find nothing but peace and prosperity for your kingdom, devoid of wars on my part."
Then, she erupted in violet flame, vanishing as if made of dust.
"I await your decision." her voice echoed, but Muller already knew the answer. As did she.
