Well, I have a new OC; Her name is Eclipse. She's a fusion (yes, you heard me; a fusion) of the two sisters, Solair and Lunair (I'll create references for them later). Eclipse has on pale blue eye, one amber eye, two tails (one tipped with ginger fur and the other tipped with silver) along with similar markings that are only different colors, representing the sun and moon.
Eclipse also has a strange marking on her chest; a circle that was gold on the right side and silver and grey on the left (You'll see the marking on her reference as well). The right side had orange flames to represent the sun, while the other side represented the moon.
She has the power to raise either the sun or the moon (or even both to cause a solar or lunar eclipse). In Ionia, many worship her as the goddess of the sun and moon.
NOTE: Now that I realize it, I made so many Pokemon Game references; references to Heart Gold and Soul Silver (or just Gold and Silver) as well as the upcoming games, Sun and Moon.
