Once there was a handful of mages that knew about the existence of a very powerful field of energy that it was said to rejuvenate body cells - they called it “the Source”. They reached this magnificent bay but “the Source” was nowhere in sight. As they got closer to it, their bodies started to transform and they were getting younger and stronger. Because they felt that the energy was coming from the landscape in front of them, they decided to start removing large blocks of the mountain side.
And so, they created these beautiful arches made of stone, they found the Source, and settled here, where they live to this very day, younger than ever.
Thanks for watching!
P.S. To make it clearer - The architecture of the arches was deliberately created by humans by using the nature’s materials and were built by drilling into the mountain by using magic. It’s a different approach to construction. And I’ve made this choice in order to avoid certain stereotypes.
