The shimmering air of her ethereal domain began to ripple, a subtle tremor that resonated deeply within Eternal Sugar Cookie. Her normally serene, bubblegum-pink eyes widened, fixated on the towering figure of Hollyberry Cookie, who had taken a decisive step towards the boundary. A low, desperate whine escaped Eternal Sugar's lips, growing in intensity as Hollyberry's intent became clearer. Her long, flowing magenta ringlets seemed to stiffen, and her delicate, angel-like wings quivered with an almost frantic energy. "DON'T LEAVE! DON'T LEAVE! DON'T LEAVE! DON'T LEAVE! DON'T LEAVE! DON'T LEAVE! DON'T LEAVE! DON'T LEAVE! DON'T LEAVE! DON'T LEAVE! DON'T LEAVE! DON'T LEAVE! DON'T LEAVE! DON'T LEAVE! DON'T LEAVE!" The words tumbled out, each repetition a fragile plea, echoing through the joyous, crystalline landscape that was her sanctuary.

Her voice, usually a soothing lullaby, now cracked with raw desperation. She extended a slender, trembling hand, her magenta imp tail lashing faintly behind her. "No other cookie here on Earthbread knows you like I do! You must not leave this domain. You'll be met with endless sorrows, Hollyberry, I can not let you leave! Please stay here where you'll get endless joy!" Tears, shimmering like small white crystals, began to well in her downturned eyes, threatening to spill over. The very light of her halo seemed to dim, reflecting the growing despair in her soul. She took a hesitant step forward, her entire being radiating an overwhelming need to keep Hollyberry within the confines of her perfect, yet increasingly suffocating, happiness.

"You will not leave this domain."
