In the black ages, the world was a quagmire of darkness and despair. Foggy forests were home to the Earth walkers, ancient beings with special powers. Among them was one who was more than mortal, an immortal named Grendel.

Grendel's father, a noble Earth walker, had been murdered. His death was a grisly affair that marked the beginning of a tragic history.

The funeral pyres had barely cooled when Grendel swore revenge. He was not afraid of the repercussions; he was immortal after all.

His father's killer was a monstrous Nephilim, a fearsome creature with a blood-curdling roar. This beast was not from the Earth but an alien from the heavens.

Grendel ventured into the stagnant weir, a place where the fallen angels resided. These beings were blinded by their own past and were feared by many.

He sought their wisdom to gain the upper hand against the Nephilim. They were hesitant but eventually agreed to help him for they too despised the Nephilim.

They bestowed upon Grendel a sacred power, one that could rival the Nephilim's strength. With renewed vigor, he thanked them and set off on his path of revenge.

As he journeyed, Grendel came across a beguiling pagan goddess who was said to have the power to foresee the future.

He approached her with respect and requested her assistance. The goddess agreed to help Grendel, foreseeing a favorable outcome in his quest.

She gifted Grendel a special black candle, its flame could guide him through the darkest of nights and reveal what remained hidden.

With the sacred power and the black candle, Grendel felt prepared. He was ready to face the Nephilim. His heart pounded with anticipation.

Upon reaching the mountain, he lit the black candle. The flame flickered, casting shadows that danced on the rocky surface.

Suddenly, the Nephilim emerged from the shadows, it's monstrous form looming in the dim light. Its roar echoed through the mountains, causing a plague of fear.

Grendel did not flinch. He held the candle high, revealing the Nephilim in its entirety. The beast snarled, blinded by the sudden light.

Seizing the moment, Grendel attacked. He used his sacred power, striking the Nephilim with a force it had not expected.

The beast roared in pain, but it was not defeated. It fought back, their battle shaking the very foundation of the earth.

Grendel and the Nephilim clashed, their power lighting up the night sky. The battle was a spectacle that would echo through history.

The struggle was fierce, but Grendel's determination did not wane. He had come too far to let his father's killer escape.

Suddenly, the Nephilim staggered, weakened by Grendel's relentless attack. Sensing victory, Grendel pressed on, his blows landing with lethal precision.

Finally, with a triumphant roar, Grendel struck the killing blow. The Nephilim collapsed, its monstrous form now lifeless.

As the dawn broke, Grendel stood victorious. His father's death avenged, he felt a sense of closure. His heart, though heavy, was at peace.

He returned to the fallen angels, the black candle in his hand now extinguished. They welcomed him with a song of victory, their voices echoing in the stillness.

The pagan goddess smiled at his success. Her prophecy had been fulfilled, and she was pleased. She vanished, leaving Grendel alone with his thoughts.

Grendel returned home, the burden of revenge lifted from his shoulders. His father's spirit could now rest, knowing his death had been avenged.

His journey had been arduous, but he was glad he undertook it. He had not only avenged his father but had also proved his worth as an Earth walker.

His tale became a legend, passed down through generations. The immortal's revenge was a story of courage and determination that would inspire many.

As the immortal Grendel looked upon the world he had saved, he knew he had fulfilled his destiny. His father would be proud.

He had brought justice, and with it, peace. The black ages had ended, and a new era had begun, an era of hope and harmony.

Grendel, the immortal Earth walker, lived on, his tale a beacon of hope. His story, a testament to the power of revenge, love, and justice.

And so, the immortal Grendel, once a vengeful son, became a symbol of strength and courage, forever remembered in the annals of time.
