Yeay, I finally managed to port the newer relation & power system from the newer v1.0 version to the beta (I can't upload this version, because its bugging too much with 1.18)
You can now overpower, you lose power on death and others can claim your land, if you have less pwoer than chunks
Relations are currently supported with war and ally.
With the HomeExtension installed, you can set homes for your allies and teleport to them
