silver banshee (earth-7)

Betrayed by her own family and erased from the world, Siobhan McDougal was cast into a dimension beyond reality where time fractured and survival meant understanding the very nature of her power. Decades later, she returns to a world that has forgotten her, no longer just the heir of a cursed lineage, but its final and most complete form, now forced to decide whether the legacy of the Silver Banshee will die with her or be reborn through her will.

Biography

Early Life

Siobhan McDougal was born into a family that carried a secret far older than their own name, a lineage disguised through generations as the myth of the Silver Banshee. To the outside world, it was nothing more than folklore, a haunting identity tied to death and misfortune. But within the McDougal bloodline, the truth was preserved in fragments and hidden records: they were descendants of the Arkanonne, an ancient alien species whose existence blurred the line between energy and physical form.

Long ago, one of these beings came to Earth and integrated among humans, beginning a hybrid lineage that would persist across generations. However, this inheritance did not manifest in all descendants. It appeared only in women, and even then unpredictably, often skipping generations as if guided by some unseen design. When it did emerge, it brought with it not only immense power, but a connection to arcane energies far beyond human understanding.

From an early age, it became evident that her manifestation was stronger than any before her. The energy within her was unstable, volatile, and deeply feared by those around her. Where previous carriers of the lineage had managed to suppress or control their abilities, Siobhan embodied hers fully, her presence alone enough to disrupt the fragile balance her family had maintained for generations.

Unwilling to allow her to take her place as the head of the family they turned against her. Using the ancient knowledge preserved within their bloodline, they opened a gateway to the Netherverse, a pocket dimension intrinsically tied to the Arkanonne’s arcane nature. It was a place outside conventional reality, accessible only through the same energies that defined their existence.

It was not an act of mercy or desperation, but of finality. By casting Siobhan into the Netherverse, they believed they had ended the Silver Banshee lineage forever, removing its most dangerous inheritor from the world without leaving a trace.

the thing

Time within the Netherverse did not move as it did in the world Siobhan once knew. It stretched, fractured, and collapsed in ways that defied logic, turning what might have been years into something far more isolating and undefined. At first, it was nothing more than a prison, shifting void that responded unpredictably, offering no sense of direction, no stability, and no escape.

The same arcane energy that composed the Netherverse flowed through her. What had been used to imprison her was, in truth, something deeply connected to her own nature. And in that realization, her survival began to change. She studied its patterns, its distortions, the way it reacted to presence and intent. Slowly, she began to understand that the Netherverse was not governed by physical laws, but by will and comprehension.

It was less a place and more an extension of the same forces that made her what she was. Over what felt like decades, Siobhan learned to navigate the instability, to anchor herself within it, and eventually to shape it. The dimension that had once held her captive became something she could influence, bending its shifting nature just enough to carve a path through it.

When she returned to Earth, the world she stepped into was no longer familiar. Time had passed without her, erasing the life she once had. The McDougal family was gone, its legacy reduced to silence. The people who had betrayed her no longer mattered, whether they had lived long lives or died forgotten was irrelevant.

She had endured a reality that would have broken anyone else, and in doing so, she had come to fully understand the nature of her existence. The records of her lineage spoke of the Arkanonne as a species, a people that once existed beyond the limitations of humanity. But now, there was no trace of them left.
