Thrall defense or alliances

Other than being in the same clan, is there a way to have your thrall archers and fighters not attack players such as setting up alliances and such?

The issue with clan is if someone leave they loose their stuff and build.

There should be an alliance system so clan different clans can work together without the Thralls killing friendlies.

If there is something in place please let me know.

Thank you

There’s nothing currently in place, but an alliance system would be an awesome addition.
