1. No hacking or unfair advantages of any kind, this includes abusing bugs.

2. Don't recreate real life wars or extremist/dictator/fascist countries from the recent 150 years.

3. Don't grief your kingdom, you may spy on each other and sabotage each other; but don't destroy large buildings and monuments in a kingdom.

4. Respect each other, no discrimination, racism, bullying etc.

5. Keep redstone & mob farms at a minimum, we're a small server with a small budget and our servers can simply not handle big redstone constructions.

6. Although we have no rules regarding building, keep the building style between the start of humanity to the early 1900's; in other words, no modern skyscrapers, airports and all that; just nice historic and early modern buildings. 

Note; Since it's a server based around kingdoms and mainly set between 20 BC and 1899 AD we support any kind of kingdom, nation and playing style.
But, like rule 2 mentions, we don't want real life conflicts of the recent 150 years to be done in our server; because it might still be politically relevant. 
Besides that, you may do everything you want; as long it's according to the rules set above. Keep using common sense though.. 

Punishment: Breaking any of these rules will result in a temporary ban for 30 days.

1. No swearing

2. No bullying, racism, discrimination put-downs, or other harassment

3. No spamming

Punishment: Breaking any of these rules can result in a temporary/permanent mute
