They crossed the finish line in second place—just behind the reigning champions, —but the team’s synergy was undeniable. Aubree felt a surge of confidence, tempered by the lingering memory of that earlier failure.

She closed her eyes for a moment, listening to the faint vibrations of the arena—the hum of the lights, the distant traffic, the subtle thrum of the city’s energy grid. She realized the rotating rings emitted low‑frequency pulses. By synchronizing the tiles’ rotations with those pulses, she could coax the Sentinel into revealing the correct alignment.

The audience erupted in applause. Kai raised his drone in salute, Lila’s holographic interface glowed with a triumphant green, and the city’s neon skyline seemed to pulse in time with Aubree’s heartbeat.

When the announcement finally came— “The Grand MissaX Challenge: Open to all. Winner receives the Crest and a one‑year research grant.” —the city buzzed like a hive. Aubree felt the familiar spark of excitement, but also a quiet whisper of doubt that had followed her since she first tried and failed to solve the in her freshman year at the Academy.

The battle erupted. Kai’s drone swarmed the Vipers, emitting EMP bursts that temporarily disabled their weapons. Lila’s hacking rig sent a cascade of false data into the arena’s HUD, causing the Vipers to misjudge distances. Aubree, using her parkour skills, vaulted over the fray, closing the distance to the pedestal in a single, fluid motion.

The Challenge’s first phase was a . Teams of three had to navigate a maze of skyways while avoiding drones that projected disorienting light fields. Aubree teamed up with Kai , a seasoned drone‑pilot, and Lila , a hacker with a reputation for cracking any firewall.
