Los Guardianes de Cádiz

In the ocean depths surrounding Cádiz, a hidden civilization of aquatic creatures guards an ancient, priceless treasure within the bowels of the Gran Teatro Falla. While the city above remains oblivious to the danger, King Azmelqarr and an elite squad led by Anaid must defend their home against the imminent invasion of the dark King Belshazzar and his army of marine predators.
