Back when we were still active on Tumblr, we answered a lot of questions about worldbuilding and other things. They are now difficult to find and there's a LOT of them, so we've gathered most No End lore, worldbuilding and character tidbits right here (amended to reflect some changes and retcons and included lore from comment section replies), so that you can read a little about the world behind the comic. This is not an exhaustive list of ALL THE THINGS, but things people have asked us. If you wish to know about something not covered here, you can always ask! We're glad to write tl;dr about worldbuilding in the comments.
Some of this can come up in the comic but most of it is just background stuff you don't need to know, but might find interesting to learn about anyway. This is a long document (30k words) divided into parts and you may want to choose to read it on Google Docs.
Most of this has been written by Kromi so all references to "I" is Kromi.
