The brief metaphysical contact of the Creator Elder Evil, Pisciiedies, the Blood Queen from the Far Realms into the Material Plane, causes a great wound to her body, causing the bloody mucus of her flesh to bleed from the Far Realm into the Material Realm. This blood creates The Eldest, the progenitor aboleth and several other, weaker aboleths. All the first generation of Aboleths in the multiverse.
