Water sprites come in a couple distinct varieties, with different fin shapes and general skintone ranges to fit their environment.
Lake/River: Their finwings are the most reminiscent of butterfly wings. They have soft curved shapes, and the patterning on them tends to run perpendicular to the many bones within the fins. These sprites have a silvery grey range of skintones.
Ocean/Tropical: These water sprites have more blue than grey in their skin, and often the pattern on the front side of their finwings is lighter than on the back. The patterning tends to run parallel to the bones in the finwings, which are slightly more angular in shape.
Deep Ocean: Elusive deep sea water sprites’s finwings are very sharp in shape, and don’t bear any patterns on their own. These sprites have very dark blue or grey skin, and the fins on their legs are more pronounced than on other varieties. Their skin and wings can light up in bioluminescent patterns for communication, and because of their deep ocean adaptation they are extremely durable beings.
