Villager Kings

Ambassadors work here to improve relations with other kingdoms (noooooo, really?). Requires paper to write flattering letters to fellow kings.

Relations level can be seen for each kingdom by clicking on that kingdom on the World Map. It is displayed as a value after the kingdom's name.
Plundering a kingdom lowers the relation by 10 points (observed from level 0 relation).

Depending on the relation level, your standing with a kingdom and their likeliness to attack you can change.
