About Astraios
Astraios sits at a rarity tier called Challenged+, and it is the highest number on this page by a wide margin. The Sol's RNG Wiki lists it at 1 in 1,750,000,000, rolled only in the Singularity biome, added in Eon 1-20. At luck 1x that is 1.75 billion rolls, or 175 million with 10x luck, and every one of them has to be spent while Singularity is active. Five creators are credited: rocca1080, artcore08, RemixCodeszz11YT, VanTomio and MI4N13.
The aura is a huge green piece centered on a dragon that floats over a pitch-black hole under the player. Light-green particles spin in a whirlpool across the floor, a star-like light glows above the player and constellations flash in and out above the dragon's head.
What makes it memorable is the cutscene. According to the wiki, the screen fades to black while text announces that the speaker devours constellations and that the player is just prey; three black holes turn green and vanish, a roar sounds behind you, the player turns to face an open mouth, and a final line says farewell before the aura appears.
