Fellswap Stories

(Surface/Multiple AUs) Red and Edge hadn't talked in years. Not since that big fight around 6 years ago. Edge now worked for the police and Red...what was Red doing? For 5 years, Edge has been seeing a shaggy black stray with a blind eye following around and now it finally is sticking around. However, at this same time, Edge is told his brother has disappeared and no one knows where he is.

Hi guys! First of all I should mention that the story pic isn't mine and of course Fellswap belongs to its original creator. A young hiker, Y/N gets lost and accidentally falls into a pit while stumbling in the dark. She wakes up to find herself in a whole new world that was never spoken of before except in children's stories. That's when she stumbles upon Barb (aka Mutt) and makes her first friend in the underground! But other monsters that live here aren't so welcoming.

Bonjour mes petits louveteaux et bienvenue dans ce nouveau livre! Ici je vais vous présenter les différentes Tara que j'ai créée ces dernières années en lisant des mangas, jouant à des jeux vidéos ou en regardant des animés/séries/films. Je vais essayer d'être la plus précise et compréhensible possible, mais n'hésitez pas à me dire ce que je peux améliorer ou ce que vous ne comprenez pas! Je vous expliquerai autrement. je précise que la majeur partie des Tara viennent d'Undertale ou de ses univers alternatifs car il y en a vraiment BEAUCOUP. Je mettrai aussi une description rapide de l'univers de la Tara décrite pour les néophytes, pas de panique! Si jamais vous voulez utiliser une de mes Tara dans vos propres fics ou que j'écrive une fic sur elle, demandez moi en commentaire ou en MP, et dites moi le rôle qu'elle doit avoir (je refuse catégoriquement qu'une de mes "enfants" soit une pute/prostituée, c'est clair?(non, j'ai rien contre elle, c'est juste... je sais pas, je veux pas,c'est tout)) J'espère que ça va vous plaire, alors... Bonne lecture!!
