Be advised and set up a flourishing society, any kind of government, rules, safety. Do not, and the world will sink into disaster.
Act the way you want, just like on a good old private Vanilla Minecraft Server with your fellow friend :
Become well-known, play as a shadow, assassinate the king, go on a trip to discover the whole History of Ulster,
smuggle, gather people to rule others by force, sell lands, be a begger, be an honest merchant, be a fence buying treasures from all around the world, grow a family.
