Each nation is on a team represented by one of these colors: Red, Orange, Yellow, Green, Blue, or Violet.
Players choose a team to join when they create their empire. Players may change teams once every 30 days but for each day a player stays on the same team, they will gain 1 point of team loyalty.
Team loyalty acts as a multiplier to any buff that the team may be receiving. So if a player has 30 points of team loyalty, they will gain +30% of the team buff.
Players may not switch to the highest populated team color within a world.
