Cethlenn, the fearsome sorceress, stands atop the highest tower of her stronghold, gazing out over the rolling hills and forests that stretch out before her. She is a proud and commanding figure, her long dark hair flowing down her back, her piercing blue eyes scanning the horizon for any signs of danger.

As she stands there, she thinks back on the long centuries that have passed since she first emerged from the Otherworld. Back then, she was a young and eager warrior, eager to make her mark on the world. Over time, however, she has become more cautious and strategic, learning to bide her time and wait for the right moment to strike.

Now, in the 1450s, she sees a world that is changing rapidly. The rise of Christianity has brought with it new ideas and new technologies, and Cethlenn knows that she must adapt or be left behind. She has spent years studying the works of the great alchemists and mathematicians of the Renaissance, seeking out new knowledge that will give her an edge in the coming conflicts.

But even as she studies, she is also preparing for war. She knows that the kingdoms of Europe are becoming more powerful and more aggressive by the day, and she is determined to defend her people and her lands from their encroachment. With her powerful magic and her army of loyal warriors, she stands ready to face any foe.

And yet, even as she prepares for battle, Cethlenn also knows that there is more to life than just war and conquest. She longs for a world where magic and science can coexist, where the old ways can be blended with the new. She dreams of a world where all people can live in peace and harmony, where the strong protect the weak and the wise guide the foolish.

For Cethlenn, this is the ultimate goal – to create a world where she and her people can thrive, where they can be free to pursue their dreams and live their lives as they see fit. And so she continues to study, to prepare, and to wait for the moment when she can make her move and claim her rightful place in the world.
