I happen to be starting the design of an adventure for my group. They are 6th level and recently entered the Shadowfell (tricked there by Sir Keegan from KotS). They happened upon a village in the Skins and freed it from the domination of a Bog Hag but replaced her with a vampire they accidently turned loose...the point of the adventure was to introduce my players to the idea that in the Shadowfell, survival trumps heroism, especially for heroic teir PCs.
So now they will be heading to Gloomwrought. They will need allies since they really are too low a level for the shadow plane. I think the Hooded Lantern will be a natural fit. So I'm thinking to involve them in a street fight of sorts, this will allow them to gain the attention of Hooded Lantern members. Below is a rough outline (pre-Flow Chart) of possible events for an adventure that will carry them through 7th level and a good way towards 8th. It will be designed to give them a patron in the city with some clues toward something sinister within the faction and will probably leave them with a choice for the last encounter (assasinate an enemy or rescue a potential friend). Right now it is rather linear. So the next step will be to break it up into some decision points.
