Alpine Lake Creator without a conscience

"So bad, huh?" Wraen remarked, hearing Tohka's vague description of her family members, but, since she was not particularly interested in hearing out the whole history of this stranger just now, she returned back to observing her reflection in the water for a bit.

"There are many stories about this, you know?" she looked up at her companion. "One of them tells of a young wolf, who was wooed by the princess of the Lake herself. He fell in love with her and agreed to go to her Underwater kingdom. They lived happily for a long time, had children and there was not a single worry in his life. Except one day, when he was out walking in the hunting grounds he chanced to see the reflection of the Earth world he had left behind." Almost like this one. 

"And he was overcome by such longing and homesickness that he persuaded his wife to let him go. Reluctantly she let him go, giving him a sealed clam as a parting gift. And told him not to open it at any cost," when this part of a fairy-tale comes in the play, you already know that there won't be a happy ending. "Back on Earth the man sought out to see his family again, except, where he had left them, very different pack resided, who knew nothing of him or his family members. He ventured to the meadows, where he had hunted, only to find an old forest there," she told and paused to fight a big yawn that had come seemingly out of nowhere.

"Things had changed beyond recognition and slowly it dawned upon this man that time here had passed way quickly than the time at his Underwater kingdom. In fact - 1000 years had gone by in his absence. Distraught, angry and unhappy, he split open the little gift his wife had given him and all the years took hold of him and he turned into dust," she finished the story and with an amused smile she added the final touch. "The moral of the story is - in case an Aqua-man or anything from a different world offers you a marriage proposal, have a full disclosure at, what it entails."
