As some areas in the world grow, others will fall. This is the foundation of the living, breathing world that is Ashes of Creation, where players will have the ability to make important decisions that matter in the longevity of an area becoming a city, or whether to siege a rival town. Rise above the ashes, create the world around you, and be a part of the story that unfolds because of your actions and decisions. – Margaret Krohn
Node sieges enable players to delevel a node (reverse its advancement) and to ultimately destroy that node entirely. This paves the way for new development and access to the locked content in surrounding nodes. Due to this dynamic, political strife and intrigue play an important role in the structure of the world.
Sieging nodes will not be an easy task for the attackers. Cities and metropolises will have a considerable defensive advantage. Automatic PvE sieges may be initiated against nodes that are not continuously active.
If you own a home in a node and you don't want to see that home destroyed, you need to defend that city! – Steven Sharif
