Hi I'm at the shadow fell portion of the campaign and I wanted to flesh each location out as much as possible.
I'm sacking off the meat of the campaign and just using the chapters as locations. I am sort of playing the campaign backwards using the doomed forgotten realms scenario where Vecna has already won and the party needs to find 7 obelisk shards in order to access the original timeline at the point in which Vecna conducted the ritual of remaking.
What happens within those locations is completely off-book apart from the final few chapters.
To that end, I've fallen in love with the sorrowsworn of the shadowfell. I considered injecting lady Shar into the story but thought it too on the nose following BG3 so I've settled with this... Loose plot where the sorrowsworn will prey on each party member's history (I've had them create secrets that are only known themselves) and allude to the general emotion surrounding that past. Lonely hungry lost etc etc. I'm definitely going to be making up some sorrowsworn emotions also to fill gaps.
My general outline will be that the players need to find out how to "fix" Castle nowhere in place for more than a moment in order to delve into it and ultimately find a return portal to the material plane.
I'm looking for any assistance, be it map/narrative advice/lore dump as there isn't much on castle nowhere besides the fact it disappears sometimes and even necromancers fear it-- Great, I'm going to be putting the sorrowsworn death knights?(Need to double check this) in there to suggest an imbalance in even the shadow plane following on from the knock in reality that Vecna has caused.
TLDR: sorrowsworn are out of control in the shadow plane due to Vecna. Trying to perhaps involve the raven queen. Want to involve castle nowhere. Story ideas please
