1. Religion: The existence of leviathans, and their ability to grant supernatural abilities, could lead to the development of a new religion or cult around them. People may worship the leviathans as deities or see them as the source of their powers. Additionally, the idea that certain people are chosen by the leviathans for special abilities could lead to a belief in predestination or a divine hierarchy.
  2. Society: The marked individuals with supernatural abilities may be looked at differently by society. They may be considered elite or have a higher status than non-marked individuals. Alternatively, they could be discriminated against or feared for their powers.
  3. Science: The discovery of the leviathans could lead to a new field of study. Scientists may be fascinated by the leviathans and study their biology, behavior, and abilities. They might also study the marked individuals to understand how the powers work and if they have any negative effects on the body. It could also lead to the development of new technology, such as airships, to navigate the deep waters safely.
