A well planned series of quests can also allow your hero to forge deep into enemy territory and resupply with new units earned from completed quests. Ruins and Sites Scattered about the map are various ruins and other sites. Ruins can be searched by leaders to discover treasures. There is a small chance the leader may be killed searching the ruin, but it is nearly always worth searching. You can discover large amounts of gold, magical items, or possibly get a few powerful troops to join your army.
Sites impart the closest town with some benefit.
This can include additional gold from mines, improved units specifications, and so forth. Sites can be destroyed by a marauding army led by a hero. This can be useful to deny your opponent a useful site on a deep raid where taking and holding the town that is helped by the site is not practical. Castles and Towns Towns are the source of wealth and new units. They generate gold each turn for your treasury to support your army and that you can use to recruit new heroes, upgrade the defenses of towns, or enable towns to build new unit types.
