I like the concept, but I agree with the poster above this doesn't sing Forgotten Realms to me. This would have been the chance to do the pseudo-setting thing (or could I even begin to hope for a new setting). We just got an adventure set in Icewind Dale as it is. Unless that introduction was just filler and not a tease of the adventures ahead, it's looking like Icewind Dale, Silver Marches, Neverwinter, Waterdeep, Hell, and maybe Tytherion.
Now hear me out, how about Tyranny of the NPCs? You spend six adventures hunting down and killing all of the NPCs you hate in FR, starting with Drizzt and the gang (ugh and Mint Julip or whatever that chick he traveled with for awhile was) in Icewind Dale and moving down the Sword Coast, ending with Elminster. Heck, Tiamat offers you half her hoard in compensation. Now that might sell...
