    Reborn as the guardian of positivity, you find yourself in a strange new world, uncertain of what it may hold. Navigating it isn't easy with gods like Nightmare and Error trying to strike you down every step of the way. But unlike the previous Dream, you have nothing to lose, and are determined to forge a better path than the soul whom you have replaced.

    After Blueberry's..'Attempt' on his own life, he's tried to find the 'Lighter' or 'Brighter' side to life - which he did, thanks to a little help of Ink and Dream. But after they helped for a while, Blue ended up befriending someone else. Which he soon falls into a relationship with, after he figures/figured out a way to calm him down. And so his Brother 'somehow' finds out about it and. .after Papyrus 'did what he did', Blue fell back into a depressive state..but someone came to help.. - This is a long awaited Sequel to my previous story 'Distant Star'. I 'somewhat' promised but promised to make a Sequel, and so..he it is. I Hope you enjoy this one as much as you did the previous.

    i was looking through tumblr (as you do) and i saw these ink headcannons and after making some of my own...well this is gonna be fun ink has a problem ...a very recent one because the once (somewhat) respected god of creation and protector of aus is now being treated like a child, he hates it, dream and blue love it, and nightmare is tired of looking after dreams sassy long lost child when he needs his nap....and dreamswap??? apparently so.

    (if you notice any adjustments in this, I'm making small changes to it :p) This fanfiction is SUPPOSED to be written FOR FUN. Most of my fanfictions are usually me putting my writing skills up to the test. However, this one is a bit... Different. No explanation. It's an Undertale fanfiction. This is an Underswap fanfiction

    Passive and Nightmare (aka Corruption) aren't two separate beings like in normal Dreamtale. Passive has been sealed deep within Nightmare, though, and with time, he starts to fade... Heads up, this is a comic.

    OK so you're gonna think I'm crazy but I had this dream (I'm talking about real me not the reader I know its a descriptions and anyway shush) where I basically became a ghost cause a Sans took my soul, but anyway since I'm obsessed with Ink Sans and whatever in the dream and had a crush on him in it (I know I'm weird) its gonna be the head-cannon in the story :T And that will be why its in the fan-fiction category. But the main gist of it is your a stranded soul/ghost where you can't talk to anyone but you can try, you can move things slightly and you can only talk to the soulless. (Example: Ink has no soul so I can speak to him but people might thinks he's crazy talking to someone who is believed to be in a coma and whatever) Anyway all will be explained in the story!~ - Cover is by me, thats why it doesn't look professional or good :T
