Our research team wanders deep into the galaxy to discover new specimens of the Galaxy Children species. Some don't seem to mind our observation. Others avoid us as much as they can. Innocent observation can become deadly interaction if we are not mindful. These majestic beings are giants compared to us and our planet. At least most of them appear to be gentle.

When Ceras first arrived in Gnatienas-A1 Galaxy, the first Galaxy Child he saw was Hiaem. Ceras invited Hiaem to go traveling with him but Nefé stepped in, being very protective of Hiaem. Ceras decided to befriend both Nefé and Hiaem and (once Nefé stopped thinking Ceras meant to take Hiaem away from her) they've been inseparable ever since.

Niko and Nefé consider themselves siblings due to the proximity of their Birth Constellations. When Niko wandered off to explore the universe, Nefé constantly worries for her and determined to make her nebula as welcoming as possible, in the hopes her sister would return.

One of Lonía's favorite hobbies is casting stars wherever she goes. She has a particular passion for making star crowns. Zetme occasionally tolerates this only because he secretly enjoys Lonía's company (but even he has his limits)

Nefé and Lonía are Nebula Attribute Galaxy Children, so the birth of a new star is very special to them. This star just so happens to be part of a Birth Constellation with a 87% chance of becoming a new Galaxy Child.

Led by Ios, Hylia and Kýp wreak havoc among a half-pack of Skiá. Most Skiá packs tend to avoid this trio due to their abnormally strong offensive abilities.
