Luna's origin

(This is a crossover of Sonic and NIGHTS)
A long time ago a baby girl was born in Nightopia. She is the daughter of NIGHTS. But when Reala and Jackles attempt to steal the baby it went terribly wrong. The baby was transported to another world (that world was Sonic The Hedgehogs world) and took the form of a hedgehog. Then Sonic and Knuckles took her in as their own after Sonic found her in the forest. A heart broken NIGHTS was in tears as Owl and Helen and her sisters were set to find her. While Luna is growing up in Sonics world on Angel island, Luna became a bright and carefree young girl to fight for what's right. What will she do if she finds out she's not what she seems to be?
