Well, the chick grew up into a chicken, but you’re still not sure how the egg got into that cave...

Ever since the moment she hatched from her woefully small egg, little Bella Luna has known she was different from all the other creatures...but she has never understood why. She has survived for many years, narrowly avoiding being crushed underfoot by the simply gigantic dragons that fill the world. Her human companion was at a loss to explain the presence of this strange little creature, and idly joked one day that she must have come from the stars for all she knew. The joke stuck, and so the human bestowed to her the name Bella Luna, which means "beautiful moon" in some odd language she's never heard of. She spends most of her time staring at the stars and visiting with the beautiful Nebula dragons owned by her human, dragons who also occupy themselves with the night sky, in the hopes that maybe their watchful eyes might catch a glimpse of any space chickens like herself.
