I don't know if anyone remembers, but a while ago, someone suggested that Raid Bosses be added to castles. There was some discussion on this as to what was the best way to implement this.
Apparently this video describes the new Raid Boss that Spawns just before the siege of Rune Castle (and that it might appear during the siege). I just wonder if NC added this because of that discussioin. Would be nice if they did.
More specifically, the boss is "raidable" a couple of hours before the siege starts. If the boss is not killed, it will assist in protecting the castle. At least that's as far as I gather.
From the info that I have heard....24 hours before a seige the Boss Appears....If not killed it will spawn in the thrown room and be aggro...aggrro to either side. Anyone that can get to hime can fight him no need to be on a side just have to be in the castle.
There are a few other instances of things that got discussed appearing later - they do read it, but they don't listen to it unless they want to.
Have you seen that movie of Charlie and the Choclate Factory (The new one[the bad one])....When ever "Mike TV" talks to Willy....Willy just tells him to stop mumbling b/c all he hears is wah wah wha wha.
