So I was looking to run this once we are done with Reavers, which we have just started.
I'm already a little nervous about the large amount of combat in Reavers Part 2 (running around the castle), and I wouldn't want to double up on that with another dungeon crawl.
Having read through the the adventure, all sorts of questions ran through my mind, questions that my players/PCs may well ask Marko (the thief).
Maybe all y'all can suggest some solutions....
Where is the prison camp (mine) he escaped from?
Where is the Cairn in relation to that?
How far is the Cairn from Fallcrest?
How did this lowly half-elf thief just walk away with the scepter in the first place? If he was trying for safety, why the hell would he poke around an obviously occupied tomb?!
The text indicates that the scepter was in the Winter King's hand. Surely it was also frozen 12 inches under the ice, like the rest of the body?
How did he get it out of the King's hand without damaging the hand?
Why didn't the Winter King - who obviously has access to very powerful stuff (skyship, zombie horde, army of underlings, regional weather control) - just stop Marko at the time?
If Marko could take the scepter...why didn't he take the Crown as well?
(My answer to this one is that as the Crown appears to be made of ice, it is nigh-on impossible to see under a foot of ice.)
So my thoughts on the scenario is that the Winter King was called that after obtaining a powerful item (the Crown) which gave great control over climate and granted powerful cold effects.
As part of the King's subsequent expansion he assaulted a dwarven stronghold, where he heard a powerful scepter was located.
As the stronghold fell, the dwarven high priest (Area 4 ghost) prayed to Moradin, offering eternal service in return for his divine intervention. Through the priest Moradin cursed the scepter.
Thus it is the scepter that is cursed (rather than the King himself), it is what is keeping the Winter King and his forces frozen.
Without the scepter in place, the King is starting to thaw, along with all of his forces. The party must return the scepter quickly, else this powerful force will return to wreak havoc on the Nentir Vale.
(I like the idea of having a thousand-strong frozen army, regimented like the terracotta army of the Chinese Emperor.)
So why does the King want his scepter back, if it will keep him frozen, unable to act?
The simplest answer is because the scepter is cursed, the King is forced to want to have it back.
Alternatively - or additionally - someone else wants the scepter returned, to ensure the King remains frozen. A dwarf cleric resident of Fallcrest who knows the history (legend) would be a good source of information.
I actually like this two-pronged approach, gives extra motivation to the PCs to take on the mission.
It also gives extra (and differing) motivations to the denizens of the Cairn, some want to own the scepter, others want it returned to the King (but only by themselves), others want to stop the scepter being returned to the King at all costs.
I would have had Marko explore an empty, completely-frozen (but navigable) Cairn. The only thing that was not encased in ice was the hand of the Winter King, grasping the scepter. Marko pried the valuable scepter from the hand without difficulty, but as soon as he did so, the tomb started (very obviously) to thaw, some places/people faster than others. Marko then freaks out and heads towards Fallcrest as fast as he can.
The main problem I am still having is the initial encounter, with the zombies and the skyship.
On its own, it's a good fight, shows the power of the King, and provides a fast, interesting, way to the Cairn.
But in general I dislike it. It's too high-fantasy for my tastes, the ship is a ludicrously powerful item, and it doesn't really fit with the rest of the tale.
My first thought would be to have a large White(?) Dragon, carrying a 'crate' which has enough space for the PCs (but no more). the undead could be crammed in there no problem (don't care about comfort, crushing, or breathing), the rest could be hanging off the outside (undead don't care about the cold).
When the PCs arrive at the Cairn, the dragon can fly off, or perhaps just hang around. Maybe the party could negotiate a return ride, not sure how that would work.
I still am uneasy about the Winter King sending in zombies to begin with.
If some of his forces are undead...why aren't all of them?
Anyway, thoughts/suggestions most welcome!
