Bernkastel, the Witch of Miracles, is an extremely powerful witch that has lived a thousand years. It is said that she lives in a world where concepts like fate and possibility can be visualized. She can give birth to all kinds of miracles with her immense power but, in compensation for that, her heart ends up breaking a bit.
