    The sequel to A Knocking at the Door! Like the actual one this time! If you haven't read A Knocking at the Door yet, I would really advise you to read it now... You would be really confused otherwise! After the skeleton brothers and Toriel have lived in the closest thing to harmony they can manage, their world is about to be changed after a human falls into the underground. (Wow... I summed it up in one sentence... Well, one sentence without spoilers that is! It's gonna get pretty crazy!) (Cover is temporary (hopefully) before I can make one, but this art does not belong to me)

    The fall lasted for mere seconds, and yet it felt like an eternity. The adrenaline rushing through your veins proved useless, as there was nothing you could do. You hit the ground with a hard thud, instantly knowing that it was very possible you could've broken a few bones. However, astonishingly, as you flexed your tense muscles, you were fine. No broken bones, but not without bruising or aches. Opening your eyes, you took in the endless black void surrounding you; and yet, you couldn't believe your eyes. And, as a hopeless feeling started to set in, your eyes fell upon a small light object in the distance. Undoubtedly, it was a home. A bright, big house in the dark abyss. Without hesitation, even in your pained, confused and terrified state, you started to set off in the direction of the house. You knew it was your only hope in a place like this. But, what you didn't know was that you were going to get much more than a shelter to stay under. Much, much more. All credit goes to Bunnymuse for the Gaster Gang! Photos not mine unless said!

    It was twelve AM on a friday night- or saturday morning. You'd just finished working a double at the bar; tired and achy as all hell, all you wanted was get home and get off your feet for the first time in fifteen damn hours. You were almost home, just one block off from your apartment; maybe if you'd left work just a few minutes earlier or later, you could have avoided what happened next... But you didn't.
