Helmi sat by Santa’s armchair, her brow furrowed as his trembling hands gripped the armrests. His iconic red hat wobbled with every shake, and his foot tapped the floor, sending ornaments rattling. “It’s getting worse,” she murmured. The doctor elves had diagnosed him with a magical form of tremor, worsened by holiday stress. The digital brain pacemaker they tried faltered, lagging behind Santa’s magic-infused neural rhythms and draining its battery far too quickly. “This won’t do,” Helmi muttered, setting the device aside.

Determined to find a solution, she crafted an analog brain pacemaker—a device tuned to work seamlessly with Santa’s unique biology, using oscillators and fluidic circuits to adapt instantly without power drain. Once attached behind Santa’s ear, the trembling stopped almost immediately. Santa flexed his hands, his smile returning. “Helmi, you’ve done it!” he said, his voice steady and clear. Helmi grinned, knowing analog had once again saved Christmas.
