I took a look at the DSotSC Area links Table. It looks like DSC004 links to the N AR0700 (which of course when I cluaconsoled there plunked me down right smack dab in the western edge of Waukeen's Promenade in Athkatla) and all the BG1 locations had become unreachable.
And to the S the link is to AR60PB (Temple of the Black Hand) which I could clua to and then return normally to Forest of Lost souls.
The good news is: Once you are stuck in the Forest of Forgotten Souls, all you need to do to get back on track is CLUAConsole:MoveToArea("DSC002") after you finish the Banshee off (or any other location, actually) and your Worldmap reverts back to normal and you can travel from area to area normally again, and you no longer get the "destination unreachable" script on the map...
