NPC Armies and Territory expansion/creep

Dungeons/locations can change with the changes of the node that controls them. So in theory, Intrepid could do a world event triggered by a node lvl up where this King appears (or resurrects or whatever, I dunno the lore) and sieges the node or just causes havoc around the node by growing his influence on the region.

Though I don't think if anything of this exact kind of event has been talked about before.

Here's more info on the world events if you're interested. https://ashesofcreation.wiki/Events

P.S. I suggest diving into the wiki as a whole and trying to find answers for your questions. It's not that you can't just ask here, but I feel like this would show you a broader and fuller picture of the game, rather than just getting the info piece by piece.

We'd have to see how nodes and guilds work out in practice in Ashes. The world is supposed to be huge and house upwards of 10k active players, so unless some guild has several thousand members (I'm sure there's at least a few of those out there) - I'm not sure if there could be "peace" on any given server. But even if there is such a guild, EVE history has shown that even such guilds can crumble under their own weight.

I would definitely like a world-sprawling mob event that lasts weeks of real time, but I'd personally prefer to see that as a huge expansion event in the future rather than a scope creep feature for release.
