Appearance
Aurora mimics the appearance of aurora borealis, in any color and anywhere on the body, including mane and tail.
Aurora can cause a "halo" effect, floating above or around them.
Just like in real aurora borealis, the markings can optionally move around and shift in color. It's entirely up to your preference if you want your character to have static or moving Aurora.
Aurora can be any colour, including colours not normally seen in aurora borealis, such as yellow or orange.
Aurora can optionally interact with other mutations, causing a bioluminescence effect by letting them glow, and can also affect patterns in the same way. Can go above or below white patterns.
Aurora can also optionally cause horns/hooves to glow, either in the colour of the character's elemental alignment or in the aurora color.
