Paladin Castles are AI castles which will randomly appear in a Parish, instead of a normal red Enemy AI castle. Unlike normal AI castles, Paladin Castles do not send out attacks and will disappear after a period of time. Villages in a parish with a paladin castle receive a small boost in popularity. The popularity received from these castles varies depending on the size of the castle. These Castles can be attacked in the same way as regular AI Castles, but players do not receive honour from destroying them.
TIP: Destroying red AI Castles should help in creating space for them to spawn in a parish.
