Kingdoms is plugin similar to Factions which provides more advanced core features and
introduces new mechanics such as turrets, structures and invasions to make the game more fun.
Kingdoms is heavily optimized and easy to use.
Currently the plugin is being constantly updated on the discord server. You can also join to get a free copy there.
If you have any questions, I'll be glad to answer. Just not in DMs.
You can see the full list of features in the wiki.
