World changes are a feature implemented in
Update 9.1. It allows for more dynamic shaping of the Tibian world. For example, a world change might pose a hazard for nature ( Thornfire) or may soak up water in river streams ( Awash). Changes can only be applied after the server save for performance reasons, and are reset back to their initial state after the next.
You can check the progress of any world change by asking a
Guide NPC, using any of the keywords: Horestis, Mage Tower, Master's Voice, Swamp Fever, Thornfire, Twisted Waters, Awash, Steamship, Horses, Overhunting, Demon War, Hive or Deeplings (official announcement here).
