The Legend of Genji (δ) - Book 1: The False Avatar

Neo-Republic City shimmers, a maze of neon and towering chrome structures. Bending hums within its very veins - powering levitating sky-cars, augmenting cybernetic limbs, fueling the relentless heartbeat of industry. But beneath the dazzling surface, a stark truth festers. The spirits, once vital and intertwined with humanity, have faded behind an unseen veil. It was the price, some say, of Korra's last great act to mend the divide between worlds. Now, the once-mighty Avatar spirit, Raava, is a shadow of its former glory, tethered to successive Avatars who find themselves weakened, and distrusted by the powers that be.

Genji, a young street urchin, is more than just a survivor in the unforgiving underbelly of the city. He's a prodigy, his mind a whirlwind of blueprints and scavenging ingenuity. When he unexpectedly manifests as the Avatar, it's not just the elements he must conquer, but the ghosts of the past - Korra's spirit, a mournful echo trapped within him, and a faltering Raava in desperate need of his aid. Worse, the city's technocratic elite view the Avatar as a relic, a destabilizing force in their carefully constructed order. To them, Raava must be eliminated.

To survive and restore balance, Genji won't simply master the elements; he'll weaponize his engineering brilliance. He'll scavenge scraps to build makeshift bending enhancers, hack into omnipresent tech networks, and turn the city's own machinery against those who seek to destroy him.
