Keo

Keo was the myrian god of the phases of the moon, which were believed by the Myri to be created by Keo constantly juggling his "moons".

Notes:
If adapted to an eastern Middle-earth setting the many "moons" should be reinterpreted as only phases of one moon, since Ambar, in contrast to Kulthea, has only one single moon.Keo could be treated as a superstitious idea vaguely based on blurred memories about Tilion.
