Seraph
SphSph / nSph
Appearance
Veilhorns with the seraph mutation will have 1 or more sets of wings. The wings will generally either be those of a bird or bat, but other variations such as fairy-like are also possible.
Seraph can be combined with other mutations to alter the wing appearance, for example the Serpent mutation can make the wings scaled and spiked like a dragon, Astral mutation can make the wings starry and lustrous, Flora can make the wings appear like leaves or petals, Lich can make the wings skeletal, and so on.
The color and patterns of seraph wings should match the colors/markings/mutations on the rest of the horse, they cannot be a completely new random color.
Feathered seraph wings may have different colors and patterns if the plumage mutation is also present because plumage can affect the colors of feathers.
