Starlight

Starlight is where the Starfall family begins for a new collector. It is a Unique tier aura from Era 6 with a base chance of 1 in 50,000, shrinking to 1 in 10,000 in the Starfall biome, which is about 10,000 rolls at 1x luck in that weather and just 1,000 at 10x. The wiki lists it as obtainable and credits Lunolve and 1nwyr. Its in-game description says the mysterious starlight will follow you persistently, illuminating the path. Kunzite, its mutation, is the rarer relative.

The visual has a bluish tint. A portal-like swirl at the feet emits two circling, gleaming beams, similar to :Flushed: but recoloured in light blue, and a star inside the player pulls blue strands of light toward itself. Star-shaped particles and white circles, probably tiny moons, fall around a character that levitates with all limbs pointing down, as if gazing at the sky. The cutscene begins as a black screen with an ominous noise and light blue glowing edges. The wiki also keeps a removed native-biome cutscene and a crafting table. No active ability.
