Sylency was born by the connection of stars and fragments of space. From an early age, she met the God of Infinity, Fumetsu, who took care of her for a while. Both didn't speak the same language, or one of them couldn't understand what was happening, but they were happy together. Fumetsu brought Sylency on the planet Zastria and went to find the Queen Astra to tell her about this strange yet magical encounter. Since Sylency was born with special galaxy markings on her ears and tail, no one knew why, but some humans decided to take care of her and find out. They made many experiments, was really the galaxy a special ability that provided immortality? Was she made of actual space and fragments of stars? Discovering the truth would make them very rich! So they started testing things out, but realizing that their attempts didn't bring them anywhere, they started treating her badly. They thought she was useless and Sylency, traumatized by what the humans were capable of, ran away from them as fast as she could. She remembers finding herself on this beautiful meadow full of colorful flowers, she was in the Nature Kingdom, and in front of her there was a castle on the clouds with a rainbow coming from it as stairs. Amazed, she started getting closer to it, but it disappeared, leaving no traces behind. Her mission was now to find the Castle again and discover the truth about herself and her powers.

She met many friends during her journey. Ryhuun is the first she met, they became best friends and had lots of fun together, or so Sylency thought. Ryhuun, finding that Sy had wings, became very jealous. She made Sylency climb off a hill, in an attemp at teaching her how to fly, but it ended up with Sy being hurt physically and emotionally. They both went to different paths, and unable to trust people she kept going on her journey. She then met Yuma, very intimidating at first, but with a heart of gold. (WIP)
