Devblog 29: Territory Zones and the fight for town cores
The August 7 announcement ties military victory to territorial Zones. An attacker must destroy the defending Keeps before a Claimed Zone becomes Contested. After it becomes Neutral, a Keep can establish the next claim. A new 
Mantlet and Makeshift Battering Ram give earlier armies additional siege options.
Keep troops supplied and recover the wounded
A wounded Avatar can crawl toward help and receive treatment with Bandages before incapacitation. Town food production moves into the Tavern, while basic equipment production is concentrated in the Town Workshop. Forest cover and regrowth also matter to movement around enemy Beacon Towers. These are the plans described in the dated announcement, not a live ownership report.
