Stellae

Stellaes, an alien race which had high connection with stars, planets, and galaxies in general; they were, generally, capable of controlling them, usually using much smaller stars and galaxies in their favor. Such is their power, that they can control matter as they wish. Much is yet to be known of them, they rarely seem interested in interferencing with other living creatures among the universes.

It's only known of one intervention with EARTH, Princess Lux Astra came once, eager to understand other living creatures in the vast universe. But she met a human man, a man that stole the hypothetical heart she had. They both engaged in a romantic relationship, that gave fruit to a beautiful hybrid daughter (Danike). 

However, things were only so good for so long for the couple, soon the Princess had to leave, as her people needed her to fulfill the role she had been chosen for.

Ever since, no other recorded interaction with EARTH has been done.
