###The pedigree of the CelestialsCelestials overall is very rare. Few have been named and even fewer have been named and killed in the Marvel Universe. No known Celestial has been identified as the head used in KnowhereKnowhere.
- However, there were once billions of Celestials in the universe and due to a conflict with another early developing race called the Aspirants and the release of a super-weapon called the Godkiller, millions of Celestials were destroyed. It is likely the origin of Knowhere is a remnant from that first conflict billions of years ago. The Godkiller was revealed in Iron Man #13.
The largest collection of named Celestials appeared in Thor #300. Almost nothing is known about them other than their names and some of their designations which were revealed in the Marvel Handbook.
The Celestial Fourth Host: Hargen, Tefral, Nezzar, Gammenon, Arishem, Jemiah, Eson, Oneg, and Ziran. Also included in the image is Thor and the Eternals in their Unimind form. A fan depiction of a scene in Thor #300 (October 1980).
- These are Celestials from a parallel universe, who seem to have the same appearance as some of the known Celestials from our universe. Their origin may or may not be the same as our Celestials.
- From what we know of the Celestials in our Universe, (in the famed Thor 300) when confronted by the power of OdinOdin, inhabiting the DestroyerDestroyer (which was imbued with the power of all of Earth's Skyfather deities) and using the fire giant's Surtur'sSurtur's magical sword, Twilight, Odin was unable to harm even one Celestial for more than a moment. The indestructible Destroyer and Surtur's sword were destroyed seconds later. The power to sunder the head from a Celestial (and make it stick) must be incalculable.
- The sundered head of the Celestial of Knowhere is not one of the named Celestials that have visited Earth (the head on the right).
