Embrace
From Wowpedia
The Embrace is an extraordinary celestial event in which Azeroth's two moons - Blue Child and White Lady - come into perfect alignment.[1] It is so named because it appears that the white moon, the Mother, is holding the blue Child. It's an extremely rare occurrence, happening only once in approximately four hundred and thirty years. Legend has it that the moons were in this conjunction when the titans created the first Dragon Aspects.[2]
