So, I created a suitable introduction to the Adventure designed for a group of characters who plans to go through the entire dungeon. I wanted a bit of a cool story to change it up from the usual delve.
Additionally, I created some simple Knowledge checks the players can make from the get go to get some information about the adventure.
The story hooks presented in the book I am still going to use, but I will introduce them to the party at Fort Inevitable itself.
Obviously, none of this is official, but I figured it may be useful to other GMs our there.
