Playing in the FR, I put things around Derlusk.
I have thus far gone:
0. A Dark and Stormy Knight - Character intro session
1. Siege of the Spider Eaters (From a recent dungeon)
2. Salvage Operation (Dungeon 123 -- party finds a map)
3. Unfamiliar Ground (again Dungeon, can't recall the issue off top of head, fairly recent) that will tie up the Derlusk area adventuring.
That will get them to 4th level. I am still trying to decide where for the next adventure, but it will most likely be something overland taking them to the region. After that it's RHoD.
If I were to do it again, I think I would just not try to make it a campaign and start off at the recommended level and give the players gold and purchase starting gear appropriate for their levels.
While it has been fun, it's a bit more work than this daddy of 2 can deal with.
