Hero Camp
Hero Camp is an adventure map object, that holds an unaffiliated hero. When a hero visits the hero camp, they will recruit the unaffiliated hero to join the player, free of charge. If the player already has eight heroes outside of towns, the unaffiliated hero is not recruited. After the unaffiliated hero has been recruited, the hero camp will disappear. The unaffiliated hero can be set by a mapmaker or be chosen randomly. A random hero will have a default starting army.
Functionally equivalent to the Prison.
