First of all, post absolutely no Kingmaker spoilers in this thread (though I will post some myself) :D
I'm a player in a Kingmaker campaign that's been running for two years. Because of a series of really stupid (meta-gaming stupid) reasons, we got TPKd in book 3 of kingmaker against the big bad.
So...
Not to go into too much detail on the TPK itself, except the only caster with dispel magic (me) was killed just before the big bad encounter because of a stupid distraction. I subsequently created a new rule for myself: "NEVER look up rules for other players during combat. It can make you forget things like how you should not walk within striking distance of a water elemental".
Vordakai can fly.
We recently started playing again, with a new party this time.
*A priest (Yod Kauken(spelling?)) we had dealings with in the first three books has taken Andamara's throne after the four founders mysteriously disappeared near Varnhold two years ago. One almost suspects HE had a hand in their disappearance...
*The Paladin's (one of the founders) wife had a baby who's now a little boy who has free reign to run around in the castle :P
*It's kinda awkward knowing about several locations which would be amazingly useful to my character without being able to go there, because my character doesn't know about them.
*Even weirder is how none of the current characters have been involved with the previous running of the country! This makes map exploration particularily weird, though we haven't really gotten to that part again, yet.
*Now we're on a mission from king Yod to investigate the goings on in the country to the west. My personal suspicion? Their "dear leader" is under some kind of magical control.
Well that's it really. It's an interesting solution on how to resume in Kingmaker after a total party kill.
