Tales of Berseria and Tales of Zestiria took place in the same world. As shown in the anime, Tales of Zestiria the X, Sorrey and his companions mentioned the story of Artorius Collbrande, the first Shepherd and Velvet Crowe, which is the protagonist of Tales of Berseria, which means that both story happens in the same world.
