In the Castle of Lumania, rests a maiden, guardian of the castle, gifted with divine grace and beauty, crafted from the bare hands of the three gods. Alexis as they call the pretty maiden. She has always praised the three gods as a sign of gratitude to them. As a gift to her, the gods gave her the gift of immorality. Through her 320 year living and spending in the castle, she never have met nor saw a mortal human for she thought that spending alone in the castle is enough for her to forget the wonders outside the castle. But what will happen if one day, she will meet a mortal man lost inside the castle? Will she fall in love with him and turn down her back to the three gods? or will she cast the mortal man out of the castle and stay loyal to the three gods?
