Highly doubt one exists i don't see anywhere that says it's against the rules to post a LFG post in this discussion
While one probably doesn't exist for Emperor directly, there are servers by popular youtubers where you can talk about things like that. GamerZakh's youtube channel, for example, has a discord server for discussion of city building, so you might find people from there.
I never said this post was wrong. Just saying that if you prefer to chat on discord, you'd probably be better off to find someone on Discord itself, rather than via here (this section of forum is mostly for support issues and quick questions, rather than gatherings ;))
