Realm
Realms are groups of up to six dominions. Every dominion is placed in a realm based on their alignment.
Your realm is your team. Every realm has a council (message board) and an Op Center for coordinating and sharing information.
You are not allowed to cooperate with dominions in other realms. Doing so is considered cheating.
Realms can appoint a monarch, who can engage in diplomacy (war and peace) and a few other responsibilities.
Realms are given a number (incremental, starting from #1) and a randomly-generated name.
