I'm excited to see that there does seem to be a healthy interest in the concept, so I'm going to expound on some of the finer details.

To be clear, this would very much be a literate roleplay and would avoid the "gamey-ness" that often afflicts Nation RPs. It could be considered a nation roleplay in the sense that players can take on the role of a more powerful revenant as well as their entourage and underlings - if they so choose.

I realize also that, in order for those interested to properly brainstorm their characters, I need to nail down what the undead are, how they work, what they are capable of, etc. To that end, I have updated the original post with some characteristics of the undead.

I have also added a map of Leria. I have included a few key geographic features and places for people to work off, but left the majority of the lands unnamed to allow players to worldbuild with fewer restrictions.

Please feel free to ask if there are any other questions.
