So here we go. Keep a look out if for this cover if you wanna to see what happens next.

Red: Red was full of spunk and determination is now a scaredy-cat because of how broken he is. When Sugar was still SOULless his attention was on Red and this was before he really got to know Dream. Sugar was very dark and twisted trying to use every method he had to break Red, so he raped, tortured Red until Red got pregnant with their child... Sugar made Red kill the child with his bare hands, Sugar kept the dust of the child as a moment-o, Red killed the child with his hands and jacket. Sugar took a chunk of bone from Red's face so Red hides the bite and cracks with the bandanna he wears ashamed and terrified of it. The chunk missing from his face is a marking that tells Red he belongs to Sugar.

Nightmare: As you know Nightmare and Horror got married, but the information was lost in the RP so I decided to end the book for that HUGE chunk of info that disappeared. Horror and Nightmare are SOULmates, meaning their SOULs are bound together. At first Nightmare and Horror became SOULmates because Horror was dying and Nightmare did it to save his life, as you share practically everything when you are SOULbound together. Like magic, HP, and thoughts. Horror and Nightmare tried for a baby, but found out Nightmare's body wasn't fit to carry them so Horror bore them instead, Horror and Nightmare are VERY passionate about their love...

Horror: Yes as I said earlier Nightmare and Horror are SOULmates, Horror is very crafty and creative so Nightmare never gets bored with him when they are on their date nights, which is why they had to sound proof their room. Horror had to carry three children, but a medical incident happened and the children formed into one single body, that child is Blazer and he has Multiple personality disorder.

Sugar/Sugarink: Sugar, he isn't dead for starters... his main reason for doing what he did to Red, Night, and Dream was because he saw some of his 'deceased' wife Melon in them, but targeted Dream because Dream had the sweet blind trust and attitude Melon did, the other reason was because he didn't want to suffer alone. Error had destroyed his AU, so he had A LOT of hate for the guy. Sugar is unstable, but he is trying his best to make up for what he did and to prove to himself he isn't a horrible guy, but so far he is failing as nobody but Dream an a very small few is giving him a chance. Sugar had altered his body to be Ink's size and he messed with his eyes to do what Ink's does, but Sugar can very painfully fix his height, but his eyes are permanent.

Sci: Not much has changed he is still that curious, stern, bossy scientist, he just dabbled in something he wasn't supposed to. Sci refuses to let Sugar touch any medical equipment, even though Sugar only wants to get the metal off of everyone, Sci has absolutely no trust in the monster and actually fears him. So maybe it is a good idea to keep the medical equipment who knows what could happen?

Killer: As you can tell Killer is more aggressive, he lives at the castle because his AU was destroyed by request, but he regrets the decision as his hearing, swell and sight are enhancing he can hear everything, causing him to be grumpy because he gets barely any sleep.

Error: Yes a lot has happened to Dream and Error, first off Error and Pj were tortured by Fate, Horror and Nightmare came to save them almost killing Horror, Pj made his first portal in and out of an Anti-VOID during this event. Sugar also kidnapped Error in an attempt to use him against Nightmare's gang, he got special metal on Error and Error still has the metal on now.

Dream: Yes Dream was kidnapped once again by our sly as ever Sugarink, but Sugarink was easier to anger as Red was free and he only had Error and Dream to watch for, but it was easier said than done. Sugarink was extremely pissed when he found out that Dream was pregnant and decided to punish Dream for it, but he took it way to far shattering and destroying Dream's arm. Dream's rescue party came, but Sugarink escaped with him and then Sugarink rape Dream, in some attempt to kill the kids as he explained what Red was like when he had to kill their child. Sugarink 'marked' Dream by biting and eating a HUGE chunk of bone off of Dream's neck giving Dream that permanent hickey. AND as the finally Sugarink attached a beautiful metal arm onto Dream as his 'reward' and there Sugarink ditched him naked, cold, and bleeding. Somehow Dream forgives Sugarink for this, maybe his innocent blind trust in everyone, or the fact when Sugar got his SOUL back he spent months trying to apologize.
Dream's kids were fine though!

Pj: Pj is eighteen, sassy, tsundere, and giving Fresh, who is three years older than him another shot.

Fresh: Handled the rescue team to retrieve Dream, but rescued Error instead.

Blackberry: Rescued out of his home, Honey had slapped him out of jealousy and drunkenness. Blackberry lives with his rescuer Classic after finally confessing himself to Classic. Blackberry gave Classic his first collar, in Underfells this is how a monster showed its love to another.

Classic: Very glad to have Blackberry living with him and Papyrus, Classic is protective over Blackberry and Blackberry is the same way back.

Blueberry: After Blackberry fled his home, Blueberry moved in with Dust.

Dust: Blueberry lives with him in his old AU.

Honey: Kicked out of Nightmare's Gang and can't even step foot inside the castle. Honey was jealous that Blackberry gave Classic his collar that Blackberry had when he was young, the got into a fight and one thing led to another BAM!! He slapped Blackberry and he can't even apologize.

Ink: Hasn't created anything, but he still doesn't know about the balance.

Night: Was Red's roommate when Sugarink had both of them captured, broke easily as his AU was gone and he had nothing else left. Night was raped by Sugarink, but he was submissive to it, Night and Red are in a relationship. Slowly but surely the old Red may come out, but he won't EVER be the same.

Blazer: Nightmare's and Horror's child, had multiple personality disorder, but the main one you see is Blazer, there is Night and Terror, Night is too shy and lazy to come out a lot and Terror only comes out when Blazer is threatened, but all three are trouble-makers.

Andrea: She is the first born and is Rem's twin. She is the outgoing one and unlike Rem she has firey hair and she was born with her marks. She is a father's girl, she strives and looks up to her father.

Rem: Rem the youngest for now, shy, cautions, and hates scary stuff, he doesn't have his tear marks yet and he has no flames. But he has very bad pixelexia like his father, but he is a mother's boy. He will do literally anything Dream says with a big smile on his face.

I hope I didn't forget anything if I did or you don't understand, I will answer your questions and add them here if they are good or necessary.
