Xorrian

Xorrians were an ancient humanoid species from Xorr, who allegedly spawned all humanoid races.

Biology
Xorrians were externally indistinguishable from Humans.

Culture and society
Little is known of Xorrian society, other than it was quite advanced, and they did not wish to abandon their planet, even when it faced destruction from a supernova.

Technology
Xorrian technology was advanced enough to create a planet-wide nuclear shield capable of withstanding the blast of a supernova. This shield emitted nuclear energies, which cause both it and whatever it is protecting to shrink in size, even entire planets. Notably, the shrunken shield can also become an intelligent humanoid being, capable of restoring what was shrunken within it by absorbing life energy and stars.

History
Xorrians existed on Xorr well over 6 million years ago, allegedly spawning other humanoid races, such as Humans, Skrulls, and Kree. At 6 million years ago, Xorrians faced extinction, as their star would explode in two centuries. Refusing to abandon their planet, they spent their last two centuries building a nuclear shield system capable of protecting them from the supernova. They managed to successfully create the system, which automatically activated once their star blew, although the force of the blast still sent the planet flying through space, the shield's nuclear energies contracting around the planet and compressing it down into a jewel, about a thousandth of its former size, becoming embedded in an asteroid after centuries of drifting, the jewel itself absorbing all the Xorrians and becoming a sapient being named Xorr the God Jewel. While Xorr tried to restore the planet and the Xorrians through absorbing lifeforms and stars, it was eventually manipulated by an Asgardian named Odin into seeking a supermassive star on the verge of going nova. As Xorr drained the star, the star exploded, destroying Xorr, and it is speculated that the remains of Xorr may have been sent back in time and formed the Lifestone Tree.
