In the town of Rotglen, the air was thick with tension. Lorcan, a Casteless boy, swept the streets diligently, his gaze often straying to the towering Black Cathedral in the distance.

His gypsy friend, Vaive, approached him, her vibrant attire contrasting the drab surroundings. She was a Slayer-in-training, protecting the town from undead threats.

"Lorcan," Vaive greeted, "How would you like to train as a Slayer?" His heart leaped; he had always dreamed of protecting his town.

Under Vaive's guidance, Lorcan's training commenced. Every dawn saw them spar, and with every sunset, they studied the ancient lore of the Slayers.

Meanwhile, in the shadows of the Black Cathedral, a necromancer prepared his sinister plan. He needed the Sacred Flame to save his dying daughter.

The necromancer, armed with forbidden incantations, summoned the undead, causing fear and chaos in Rotglen. The town needed its Slayers more than ever.

The Slayers, led by Vaive, fought valiantly. Lorcan, despite his novice status, showcased bravery, taking down multiple undead creatures.

Despite their efforts, the numbers of the undead grew. The necromancer, hidden, watched in satisfaction as his army overwhelmed the Slayers.

The necromancer then ventured into the Black Cathedral, where the Sacred Flame was kept. He managed to unlock its chamber, his intentions clear.

Fear gripped the town as the undead advanced. Vaive and Lorcan, undeterred, continued their fight, inspiring others with their courage.

Lorcan, sensing the Sacred Flame's displacement, rushed to the cathedral. The necromancer, however, had already harnessed its power.

Lorcan confronted the necromancer, the Sacred Flame burning in the man's hand. But, overpowering him seemed an impossible task for the young Slayer.

As the necromancer prepared to strike, Vaive joined Lorcan's side. Together, they managed to wound the necromancer, creating an opening.

Seizing the chance, Lorcan wrestled the Sacred Flame from the necromancer, the flame transforming into a part of him. The undead army outside faltered.

The Sacred Flame, now a part of Lorcan, granted him immense power. The glow of his eyes matched the flame's intensity as he prepared for battle.

Empowered, Lorcan clashed with the necromancer. Their battle echoed throughout the cathedral, the outcome hanging in the balance.

Meanwhile, Vaive held the undead at bay. Though outnumbered, she fought with all her might, trusting Lorcan to defeat the necromancer.

In the end, the Sacred Flame's power, combined with Lorcan's courage, proved too much for the necromancer. He fell, defeated and broken.

With the necromancer's defeat, his undead army crumbled to dust. Rotglen was saved, and hopes were rekindled in the hearts of its people.

Lorcan, once a lowly Casteless, was now viewed as a hero. Vaive stood by his side, proud of her friend's transformation.

The Sacred Flame, an integral part of Lorcan now, offered him a newfound purpose. He vowed to use his power for the betterment of Rotglen.

The brave Slayers were honoured by the townspeople, their names echoing in every home. Their courage had restored peace and hope to Rotglen.

Lorcan's journey from a humble Casteless to a heroic Slayer was now a legend. His story served as an inspiration for the budding Slayers.

The Sacred Flame's power brought a fresh dawn to Rotglen. It served as a beacon of hope, promising protection against all evils.

The memory of the necromancer's attack would fade, but the tale of Lorcan and Vaive, the protectors of Rotglen, would forever be engraved in its history.
