Summary
Things are working smoothly (are they really?), everything's going good (is it?), then life finds a way to mess it up.
Sometimes, all you need to improve is your past self to show up in your house and annoy the shit out of you.or;
Nightmare's an asshole, so I force character development on him.or; Dreamtale canon is written via a children's storybook, isn't that interesting?

Summary
Dust was on his couch after yet another long day at work when he saw a blinding flash of light in his garden. Getting up he slowly approached the bay window to take a look outside... and saw four strange skeletons dressed as a viking, a noble, a knight and a Roman yelling in foreign languages at each other.
He didn't know why he opened the window nor why he invited them inside, but he did, and by doing so he sealed the beginning of a very weird adventure with his four new roommates...
Dust - Modern Time, speaks English
Horror - Scandinavian Viking, speaks Old Norse
Killer - Ancient Roman, speaks Latin
Cross - Medieval Knight, speaks Old French
Nightmare - 17th cent French Noble, speaks Classical French(Cross-posting on Tumblr ! @/mikimakiboo
Basically a story about the boys coming from different time periods and time traveling together
Short chapters but it allows me not to burn-out too fast :')
Also, time being what it is, I should specify that I did NOT use AI for anything in this story, the languages all come from long researches to translate word by word in some cases, I did it all myself without the use of AI)
