You can actually find out a lot of information in this General Luna section of the forums:

There is also a domain section of the forums for Luna that has peoples posts about said domains.
As it currently stands our server has had our monarchs all select their kingdoms so we have been able to create maps and do further planning for the rest of our placements. You can find those maps on this post for each server:

Here is the one that I did specifically for our server though if you don’t want to check out that link!
I truly hope it helps and if you have any questions don’t hesitate to ask!
