Heroes' shrines are monuments for Heroes of your realm. They are raised on unused plains. Heroes' shrines attrack traveling heroes, who may decide to follow your cause. The propability for a hero to pledge loyalty at a shrine is 1.0 % and increases with every tick by 0.2 % until a hero appears at the shrine. Afterwards, the shrine belongs to that hero. If the hero dies or is dismissed, the propability restarts at 1.0 %. The higher the expansion level of the shrine, the more experience the hero gains during combat. If the home shrine of a hero is lost, than the hero is reassigned to a unoccupied shrine. If there is no unoccupied shrine, then the hero remains without shrine and doesn't gain any experience in combat any longer. If a shrine is conquered while a hero is waiting on that field, the hero disappears from the map (but is still shown in the unit summary) until another shrine becomes unoccupied. The hero is then reassigned to that shrine and may be assigned to an army from there. All heroes start at level 10 and can only rise to higher levels by combat.

Hints by experienced players
The sooner you have heroes, the stronger your armies will become. If a hero appears in your realm those abilities don't quite fit to your game strategy, then do not hesitate to dismiss the hero. Maybe the next hero will be a better match. It is not necessary to send a full army to retrieve a hero from a shrine. A single horsemen is sufficient and often much faster.
