Veles is the Slavic god of the underworld. He is chaotic, representing water, earth, and animals. Veles is in opposition to Perun, the supreme god of war and thunder and ruler of the skies. In a myth explaining the changing of seasons, Veles steals from Perun every year, and they fight until Perun wins. When Veles falls back to earth, it rains and life regrows.

Mermaids are cross-cultural mythical beings that dwell in the water. In many European myths, they are restless creatures that are considered to be bad omens. In other myths, they lure people away with their beauty or music. Their stories often serve as a warning to tread carefully in water.
