Yeah, I think you know what to do. Remix this, change the word up a bit but not a ton, try to have some logic but have fun. Change the meaning if you want over time, and derive words from it. Remixes do not need to happen in a chain, meaning three people can remix the same one if they want and cause the language family to branch out in three ways. Keep this background color so we can keep track of what words are related
Let's say this language tree is not related to the other one because that would be too hard, but if you want those languages to have any influence on these ones, go ahead and have fun. For continuity's sake we'll just say this language family is younger than the first IWE tree.
