An 18th century map that hides a secret. A letter written by a man at death's door. The ancient legend of a city sunk beneath the waters of Lake Antela. Ancient towers that guard the borders of a different world. A world where armies of mosquitoes still hide and await their King Arthur. A world in which time does not exist. A world in which, if you find the entrance, you will achieve something unimaginable: immortality.
