So, Steven has said in multiple interviews cited on the wiki that the Castle Node Sieges in weeks 1, 2, 3 and the Castle Siege itself in week 4 are "automated/happen automatically", what exactly does this mean? What happens if there are no attacking guilds that sign up for the weekly sieges or no guilds declare siege during week 4? Does the castle get sieged by NPCs? Does the castle owner get a free month? If uncontested, do they have to do anything?
I've done a lot of digging. Can't find the answer.
