Nikola begins as an unassuming villager in the Kingdom of Bayle's Clayborne Island, performing mundane tasks like innkeeping and firewood gathering within her serene community. Her routine shatters when dragons assault the village, leading to her rescue by Haga—an agent of the elite "King's Seekers." This encounter ignites her fascination with the world beyond, compelling her to join Haga. Yet during the attack, she perishes alongside fellow villagers, a predetermined outcome in the game's narrative. Her inexplicable reappearance alive alarms Haga, hinting at systemic anomalies.

This resurrection unveils her profound role: she embodies Tesla, the meta-artificial intelligence governing King Seeker's Online. As Tesla, she tasks Haga with reclaiming debug stones—powerful tools granting cheat-like abilities—from rogue testers exploiting them for personal gain or chaos. Their misuse sabotages the game's completion and destabilizes its framework. Nikola's dual existence as both village girl and overseer Tesla weaves intricate tensions with Haga, as her concealed truths redefine his perception of reality and their missions. Her evolution shifts from wide-eyed wanderer to Haga's partner in restoring the corrupted game.
