They died. They had died alone, scared, cold.... only to reborn in a new life, as royalty of all things! Things were confusing, and scary, and maybe she should probably be a little more self aware. However Crescent was a kid, a kid who longed for her family's love. A child who longed for companionship and was terrified of being alone and who had a target on her back simply because of who her parents were. Her loving parents, who she would get confusing signals from. Hopefully she would survive in her new life...

Complete This is a semi Fgod story (I don't know what defines a fgod story) Error has been hurt for a while now. And Destiny has had enough and makes a friend for him. But what happens if Fate finds out? Might have slight gore but none at the beginning. Sorry if this is bad this is my first book. I might rewrite it later. Also the cover is mine These characters are not mine they go to their respective artists. Except Beth and Paw they are mine. I'm not shipping anyone in this story.

Someone from our world gets transported to an undertale AU as Napstablook! Well it can't be that bad right? Minus possibly getting stuck in a FGOD or FGOC Multiverses? But, who said that's the case? This is my first story so it might not be that good.... if there and any mistakes please tell me in the comments!

~ Dream was born 21 years after Nightmare was. Right after he was born, he was already titled as the 'Guardian of Positivity'. Quite too young for a child like him. But Nightmare taught him everything he needs to know once Dream is around 4-5. Dream didn't care at first, but the longer it gets the crazier the requests got. Nightmare knew what the villagers using Dream for and it drove him nuts. Nightmare bit the apple and there it is. Corrupted Nightmare. Known as Paralysis. Nightmare convinced Paralysis to not kill Dream and raise it like one of his own. And Paralysis did so. He might look evil but he has a kind heart. Read more to find out what'll happen next! Again, this is a remake so don't ask me if I've done this before. (Anyway the old one was deleted because it was really problematic and I hate it.) (( COVER IS CURRENTLY IN THE PROCESS ))

Cross jumped off the cliff. The last thing he saw was his friends being put in hand cuffs by Swap and Ink as Dream looked at Cross in disapointment. "This was your choice? Then deal with the consequences." She said. Out of all the things Cross expected to see in the ocean, a merman wasn't one of them. Much less four. ~~~~~~~~~ Barely anything goes with the cannon. I bullshited everything! She/Her Dream because I can Sideships aren't tagged because I dont want to give them away This is a Crossmare fanfiction. If you dont like the ship, don't harass me or any of the readers, just move on, because your comments will be deleted
