It is a beautiful spot on the beach, always clear of any sign of trash with warm soft sand which opened up into clear blue water it is always welcomed by those people who find this hidden spot.
On the surface, it is all anyone could want, isolated and clear of any crowds of people who could ruin your peaceful day at the beach. Its sand is always soft, free of any small rocks which could get in the way of kids or adults making sandcastles or sunbathing. With high rocky cliffs forming a large U shape going out into the water, it cuts people off from the outside world allowing those who come to its shore to get lost in time, there is what looks to be a clear path down from the cliffs to the sand covered beach welcoming those who find it in.
And once in, they never leave.
For this beach is no ordinary beach, like a Venus fly trap plant it is designed to lure people in and once in they walk in, they never walk out.
For this beach is a magical doorway between the human world and the world of mermaids, merman and other magical sea creatures. Once a number of humans within it’s welcoming sand, the path leading out will disappear and without the humans within noticing they would find themselves transported to the magical ocean world. Once there, the next phase of this trap would begin, for entering the waters of said ocean will begin the process of transforming the humans into one of the many types of mermaids, merman or another type of magical sea creatures. The strong magic is not limited to transforming into merpeople or other creatures, it can restore youth or change genders of those who walk into this magical trap and more so once it has transformed one group of humans it will reappear again in the human world be it in the same spot or another spot around the world to repeat the process all with the hope to grow the merpeople population in the other world.
